I know what you mean. I'm 46, not really experiencing any obvious symptoms. Like you, slightly worse sleep and can get very low mood during PMS - but I'm also concerned that if I don't go on HRT then I'll be missing out on the benefits you describe.
I don't feel I warrant a GP visit yet concerning peri - so, I'm not sure what the answer is really.
It’s really frustrating due to lack of sufficient scientific research. I really feel women are all having to experiment on themselves to find out what works. I’m your age and looking back am convinced I entered peri somewhere around 39 when my periods suddenly became significantly heavier. Over the years I got tested and given different meds for making them less heavy which made no difference. Then 2-3 years ago period pain became something else to the point I’d throw up from the pain and dreading it every month. All scans/tests came back as normal. Add to this sleep issues, random joint pains, tinnitus, anxiety- I really had had enough.
As soon as I turned 45 I asked my GP to be put on HRT. However after a year on it and trying different types and strengths it made next to no difference to most symptoms with added bonus of random side effects. Worst of all I started putting on weight like never before having been the same weight for over 20 years.
One day in March this year I ripped off the HRT patch and never looked back. Instead I’ve been intermittent fasting consistently ever since. Since April my periods normalised to the point I hardly notice them now. I’ve lost the weight and feel more myself than I have in years. I take vit D and evening primrose oil as well as use a magnesium spray before bed. It’s taken time but sleep is much much better, anxiety is almost gone, aches and pains gone.
HRT works for loads of women for sure, but may not be suitable for everyone. The link between hormone imbalance and insulin, as well as conditions such as oestrogen dominance are really fascinating.
