I'm 48 and now in menopause (month 7 with no period). I started peri-menopause (or as I like to refer to it "pre-pause") when I was 42. Night sweats, hot flashes, mood swings out the wahzoo... some months I'd have a real light period, some months very heavy, some months not at all...
Here's what helped me the most!!

At the very least... just hop around the site, read! Read! Read! - LOTS of information there!!
It's NOT a gimmick. I tried their
Herbal Equilibrium pills and I swear it worked for me. No more hot flashes (or at least, very mild ones & way less of them!) and night sweats? - zippo! It took about 3 months for it to kick in, tho - and that's just "my personal experience".
I did go off them for a while about a year ago. But after about 6 or so months, I was fed-up with my whack-hormones & went right back on them! - And I still take them now.
I swear, I can't say enough good about it. But hey, see for yourself. It may or may not work for you. But I'd at least give it a try!
Good luck!
