FOR WOMEN 35+ WHOSE PMS, PERIODS, MOODS AND ENERGY HAVE STARTED BEHAVING STRANGELY
Feel like yourself again in perimenopause
There's another way through this phase of life, and it starts with what you eat, drink, and do. Not more restriction or another supplement, but sustainable changes that give back your mood, energy, and sleep.
Lifetime access. Self-paced. Opens late October 2026.
You’ve done the research on perimenopause
You’re the one your friends come to when they need something figured out.
And yet at 11pm you’re still Googling “why is my PMS suddenly so bad”, closing seventeen tabs that all contradict each other, and wondering how you can be this capable in every other part of your life and this lost in your own body.
The week before your period has become something your whole family braces for. You snapped at someone you love over something tiny, and the guilt lasted longer than the argument. Your period arrived heavier than it’s ever been. The wine and cheese you’ve enjoyed for twenty years suddenly disagree with you. And the energy you used to rely on is just... not there.
You’re not imagining any of it. Something real is changing. It just hasn’t been explained to you properly yet.
So you did what all capable women do
You downloaded the cycle app. Bought the supplements a stranger on Instagram swore by. Cut out the foods that seemed to upset your gut, then a few more to be safe. Went to bed earlier. Pushed through the PMS week and apologised afterwards.
Maybe you took it to your GP and heard “your bloods are all normal”, “it’s just stress”, or the classic: “you’re too young for perimenopause”. So now you have symptoms that are apparently caused by nothing, a body that stopped following the old rules sometime around your 42nd birthday, and a quiet 2am suspicion that maybe this is just who you are now.
Add up what the guessing has cost: the supplement graveyard in your pantry, the ever-shrinking list of foods you trust, the mental load of piecing together advice from podcasts, reels, and your sister-in-law. It’s probably already more than the price of this program, and none of it was built for a perimenopausal body.
Here’s what nobody has told you: the rage, the flooding periods, the food reactions, the 3am wake-ups. They’re not separate mysteries. They share drivers. And it’s not you failing to cope. It’s a strategy that was never designed for this phase of life.
You’re not all out of options.
Your body is having trouble adapting to changing hormones, and there are concrete reasons why. Which means there’s something you can do about it.
When you understand what’s actually getting in the way, and support your body with the right foundations, it can adapt.
INTRODUCING
PerimenoGO
PerimenoGO is a self-paced program where you finally make sense of what’s happening in your body during perimenopause, and learn the guiding principles for what to eat, drink, and do that help it adapt, so your symptoms can settle and you can feel at home in yourself again. Without restriction, and without giving up the parts of life you enjoy.
It’s the manual for caring for your changing body that no one ever gave you.
What’s inside
Everything unlocks immediately, and you move at your own pace. Four modules take you from understanding what's actually changing in your body, to putting the principles into practice with what you eat, drink, and do, and sustaining them for the long term. Every lesson is bite-sized (all under 10 minutes, most just 3 to 5), with transcripts, guides, four weeks of meal plans, and printables along the way.
01
Module 1: Make sense of how you’re feeling
What’s actually changing in your body, why the PMS escalated and the old rules stopped working, and what’s common versus what needs checking. You’ll set your baseline and choose three non-negotiables.
Outcome: the “am I going crazy?” question answered with physiology, and a starting point that’s yours.
02
Module 2: How to eat
The PerimenoGO food principles: guiding rules instead of rigid meal plans, everyday foods versus occasional foods, and protein, carbs, and fats made simple. Comes with four weeks of meal plans, recipes, shopping lists, and a plate guide for the nights you don’t want to think.
Outcome: you know what to put on your plate, and why, without counting anything.
03
Module 3: What to drink and do
Caffeine, alcohol, and the drinks that quietly make symptoms worse (with realistic swaps, not bans). Plus the minimum effective lifestyle supports: sleep basics, stress resets, and movement that helps instead of punishes.
Outcome: the biggest non-food levers, sorted, in under a week.
04
Module 4: Make it your new normal
Busy days, social events, takeaway nights, and what to do after a wobble so one off day doesn’t become an off month. Plus how to tell whether foundations are enough for you, or whether your body needs deeper investigation.
Outcome: a way of eating and living you can do, even during Christmas, holidays, and a busy life.

BONUS: the PerimenoGO community
A private community space for encouragement, accountability, wins, and questions, with women doing exactly what you’re doing.
Because doing this alongside other women beats doing it alone.
Lifetime access. Self-paced. Opens late October 2026.
This is for you if...
- You’re noticing the early-to-mid signs: worse PMS, mood swings, heavier or erratic periods, gut niggles and new food reactions, flat energy, dodgy sleep, and you want to get ahead of it rather than wait for it to get worse
- You’ve been told “everything’s normal” or “you’re too young”, but you know something has changed
- You want to understand the why, not just be handed another set of rules
- You’re willing to make realistic changes to what you eat, drink, and do, if someone shows you which ones actually matter
- You want an approach that survives family dinners, work events, and an actual social life
It’s not for you if...
– You’re looking for a quick fix that doesn’t involve changing anything
– You want a practitioner to build a plan for you personally (that’s my private program, The Chaos to Calm Method, not this one)
– Your situation is complex and you already know you need testing and 1:1 care (check out The Chaos to Calm Method, and start with a free Clarity Call instead. I’ll point you to the right level of support)
Real women, their real words
I’ve spent nine years in clinical practice helping hundreds of women across Australia, NZ, and the USA through perimenopause. PerimenoGO is the foundations layer of exactly what I teach my private clients, the women who tell me:
INTRODUCING THE CREATOR:
Sarah McLachlan, The Perimenopause Naturopath
I’m Sarah McLachlan, The Perimenopause Naturopath (BHSc Naturopathy, BSc Psychology), a degree-qualified naturopath who’s specialised in perimenopause since 2017.
I do this work because I’ve lived it. In my early 40s my body started changing: my immune system turned reactive, I developed coeliac disease and allergies seemingly overnight, my periods got heavier, my PMS got worse, and my mood didn’t feel like mine. I was told I was too young for perimenopause, so I kept pushing through, and missed the chance to support my body earlier and more gently. When I finally understood what was happening and gave my body the right support, everything shifted. My energy came back. My mood settled. I felt like me again.
PerimenoGO is the program I wish someone had handed me at 40. It’s also a homeschooling mum-of-four’s program, which means it’s built for real life, because mine doesn’t have room for complicated either.

Questions?
How much time does it take?
The lessons are bite-sized, all under 10 minutes and most just 3 to 5, and you work through the four modules at your own pace. It's designed for women with full lives and low spare energy, so you can go as slow or fast as you like. It's yours for life, so there's no rush.
I’m not sure I’m actually in perimenopause. Is it too early?
If your body is starting to feel different, it’s not too early, it’s ideal timing. Perimenopause can start years before your periods change noticeably, and the foundations are easier to lay early than to repair later. Getting ahead of it is the whole point.
I’m post-menopausal. Is it too late?
No. The foundations, food, drink, sleep, stress, and movement, matter on the other side of menopause too, especially for lingering symptoms.
Will this fix my symptoms?
Honest answer: PerimenoGO builds the foundations, and for many women that’s enough to feel noticeably better. Some bodies need more: proper blood work, deeper investigation, personalised care. If that’s you, you’ll know by the end of the program, and there’s a clear next step (and needing more isn’t failure, it’s complexity).
Do I have to give up carbs, wine, or my social life?
No. No food groups are cut, nothing is counted, and the program includes strategies for eating out, celebrations, and holidays. Strategy beats restriction. That’s the whole point.
How is this different from working with you privately?
PerimenoGO teaches the principles: the foundations that help every perimenopausal body adapt. My private program, The Chaos to Calm Method, builds YOUR plan: blood work, functional analysis, and a precisely personalised strategy, built with me. Most women start here, or with the small group version of my private program, The Chaos to Calm Method (Together), which is launching late October 2026.
How long do I have access?
Lifetime. Buy once, keep it, come back to it in any phase.
