I'm 42 and think I'm in perimenopause, too. My periods were always very regular, then a few years ago they started coming every 3 weeks instead of 4 for awhile. Then back to 4 for awhile. Has been going back and forth like that since. Plus now I have very bad anxiety. I just had a fire 6 months ago, though, so am not sure if it's from ptsd or perimenopause. I've bought some Estroven, the formula for mood and memory that is supposed to help with perimenopausal anxiety, just in case I could be having some of that. I also get night sweats, and it's supposed to help that, too. The problem is that it is natural and takes up to 2 months to start working - very slow. I just started it a couple weeks ago so still feel about the same. Plus I've never had much luck with natural remedies but figured it was worth a try.
