We can all relate to that post-holiday feeling. You’ve enjoyed a blissful few weeks where you forgot about your diet, ate and drank what you wanted, took time off from exercise, and generally enjoyed life to the full. All the while, you tell yourself that when you get back, you’ll pick up exactly where you left off, or push even harder to make up for the holiday excess.
So your first Monday back rolls around, and you’re determined to return to your usual routine: morning walks, exercise, balanced meals, and an early night. But often the reality is very different. You’re wide awake in the early hours, exhausted by mid-afternoon, feeling guilty for letting things slide, and quietly irritated with yourself for not bouncing back immediately.
Here’s what more women should know: this is completely normal. More often than not, it isn’t a discipline problem or because you’ve suddenly let yourself go. If you’re in your forties or fifties, your body may be dealing with two separate factors at the same time that can contribute to this feeling, and neither has anything to do with discipline.
Why the post-holiday reset feels harder than it used to

The first thing to consider is that your body doesn’t run on dates; it runs on rhythm, and it takes its cues from the timing of your daily routine, for example when you wake, when you eat, when you exercise, when it gets dark, and when you finally stop for the day.
A holiday can scramble almost all of those at once because it plays havoc with your routine. Differing bedtimes, later meals, different food at odd hours, more alcohol, a lack of or increase in exercise, and a stretch of days where nothing happens at the same time twice. This isn’t your fault, as it’s what holidays are generally all about, but it does leave your system’s internal clock without much to go on, and a system that’s out of sync can take longer to come back than a few days of being good allows.
Another factor to consider is that in the years around perimenopause and menopause, fluctuating estrogen and progesterone already make sleep lighter and more easily broken. This means that a holiday disruption isn’t being dealt with by a rested system; it’s landing on one that was already working harder than it used to.
This is far more common than most women realize, largely because so few of us talk about it. Research published in the journal Menopause in 2025, drawing on survey data from nearly 48,000 perimenopausal and postmenopausal women across the United States and five European countries, found that sleep disturbances were reported by around 61% of perimenopausal women who also experienced hot flashes or night sweats, and by roughly 38% to 41% of those who did not. Sleep disturbance was independently linked with lower quality of life and higher scores for low mood and anxiety, whether or not hot flashes were part of the picture.¹
So if you feel more scattered and more tired than the holidays alone should explain, perhaps you shouldn’t be so hard on yourself.
Why starting again on Monday tends to fall apart

The instinct is usually to go hard once you return, and that’s a lot to ask all at once. You overhaul your food intake, add intense workouts, cut out everything enjoyable, and start the Monday after you get home. That places an enormous amount of pressure on your first day back, and while it can feel decisive, it also asks your body to absorb multiple major changes in the week when your energy is at its lowest.
There’s also a problem with the way this is framed because when the reset becomes about earning something back or making up for what you ate, it stops being about how you want to feel and starts to feel like punishment. That approach rarely lasts past the second week, and it can leave you feeling worse than when you started.
Now let’s talk about Monday.
Whenever we want to change something, whether it’s a new year, a milestone birthday, or the first week back from a holiday, the instinct is to set a start date after which it’s all or nothing. From January, I’m going to stop drinking. After my birthday, I’m going on a diet. Next month, I’m going to exercise every day. But every start line you set is also a deadline, and the days in between fill up with dread rather than progress because that date ends up carrying far more pressure than it needs to. If the change you’re planning is meaningful and achievable, why not start today?
So do one small thing today instead, not the whole overhaul, just one small habit you can build on. It takes the pressure off the date you’ve set yourself, removes the blame-shaming, and lets you arrive at Monday already underway, feeling like you’re ahead, rather than feeling like you’re making up for lost time.
Evidence doesn’t tend to support the crash approach either; in fact, a 2024 systematic review and meta-analysis published in Healthcare, covering 20 studies and 2,601 participants, found that health-related habits took medians ranging from roughly 59 to 66 days to establish across the studies reviewed, with individual variation ranging from 4 days to 335. Habits practiced in the morning, and habits people chose for themselves rather than had imposed on them, tended to take hold most strongly. The popular idea that three weeks is enough does not hold up, which means a seven-day crackdown is unlikely to work.2
5 steps to get your routine back on track

- Stabilize the time you wake up
Pick a time and keep it roughly the same every day, even on days off. Consistency matters as much as total hours.3 A 2025 study also linked steadier day-to-day sleep timing with better mood, and the association appeared stronger in women than in men.4 In short, get your sleep, ladies! - Eat protein reasonably early
The aim here is to give your body something steady to work with in the first part of the day, so that by mid-afternoon you’re making decisions from a stronger place, rather than a depleted one. - Move in a way that lowers stress rather than adding to it.
A walk or a resistance workout both work, as long as it’s something you can sustain in the weeks after your holiday rather than use for a quick fix. If exercise is there to make up for what you ate, it’s moved into punishment territory, and that rarely helps. Keep it positive and make it something you look forward to. - Rebuild your last hour of the day
This is usually where holiday drift lingers longest, and it’s the one most of us skip. A consistent wind down, with the screens and the wine given a little less room than they had during your holiday, does more for how you feel at 7 am than almost anything else on this list. - Give it eight weeks, and stack rather than bulk start
Build the new habit onto something you already do reliably, rather than creating it from nothing. Judge it in months, not days, because that is honestly how long this tends to take.
Support your post-holiday routine comeback

Getting your rhythm back is a key part of your post-holiday reset, because it’s the foundation everything else builds on. But your natural rhythm takes time to rebuild, and the first few weeks can be the hardest.
You may be trying to protect your sleep when your energy is low, while also feeling more irritable than usual and digesting richer, later meals than your body is used to. This is often when good intentions start to fade, not because the plan was wrong, but because your system is still under strain.
That’s where the Hormone Reset Kit from Happy Mammoth comes in. Hormone Harmony is a plant-based blend that includes ashwagandha, chaste tree berry, chamomile, and fennel, plus vitamin B6. Ashwagandha helps the body deal with stress and helps maintain emotional stability; vitamin B6 contributes to the normal regulation of hormonal activity, and fennel and chamomile support overall digestive wellness. Hormone Harmony PLUS+ adds selenium and iodine to support thyroid function, with iodine also contributing to energy metabolism.
Both formulas require just three capsules a day, making them easy to build into an existing morning routine. See full ingredient and dose information. Getting back into your rhythm does not have to feel like punishment.
It’s just a rhythm, and rhythms can be rebuilt.

Frequently asked questions
About Hormone Reset Kit
How do you take the two formulas together?
Each formula is three capsules, taken once a day, and the capsules are small enough to go down easily with a glass of water. You can take them at the same time or separately, whichever is easier to remember.
Is there a best time of day to take them?
Morning tends to work well for most women, mainly because it attaches the habit to something already established. That said, any time of day that you will actually stick to is fine, or follow the guidance of your health practitioner.
Is the kit suitable for everyone?
No. Neither formula should be used if you are pregnant, may become pregnant, or are breastfeeding, and they are not recommended for children under 12. Hormone Harmony contains chaste tree berry (Vitex agnus-castus), which may interact with hormones and with medications including oral contraceptives, so speak with your health professional before starting if you take any regular medication. Hormone Harmony PLUS+ contains iodine and selenium, which support thyroid function. If symptoms persist, please see your health professional.
Is there anything I should know about the ashwagandha?
Hormone Harmony contains ashwagandha. Check with your health professional first if you have a thyroid condition or take thyroid medication, sedatives, or medicines affecting the immune system. Stop use and seek medical advice if you notice yellowing of the skin or eyes, dark urine, or unusual tiredness.
