Actually the belief that menopause starts in your late 40s to early 50s is being changed. The infamous "they" are now saying it can start in your mid to late 30s. I started having night sweats and migraines about 35-36 but didn't actually have any changes in my period until I was 46. I had my last period at 47 but the hot flashes/night sweats (which are just hot flashes at night - wonder why we have to give it a seperate name? lol) have gotten worse since then. (I'm 48 now) My naturopath put me on Progesterene Creme and Vitex and things are getting better. Like I told him - I don't mind the hot flashes during the day.....just drink some ice water, but at night - wake up soaking, throw off the covers, fall back asleep, wake up 20-30 minutes later freezing cold, pull covers on, fall back asleep.....start all over!
