Perimenopausal stuff has been going on for me for 18 months. All pretty typical, looking on here. Mainly it seems to mimic a lot of things that I have experienced only during pregnancy - which wasn't long ago, as I had my kids at 39 and 42, and I am now 45. Anyway, latest development, having led a very charmed life of more or less zero headaches, appears to be return of flashy light visual migraine (prev only had when pg) and now crashing headache / nausea. I had a glass of wine the other night and feel like I'm really sensitive to dehydration - again something I experienced whilst pg. So thinking even small amount of alcohol best avoided. Just wondered about your experiences and views
