48 and perimenopausal here too. Sometimes I have 1.5 periods, sometimes I have night sweats, sometimes I have hot flashes and I definitely have mood swings every month. It's crazy. Sometimes I have terrible insomnia too. My anxiety is often triggered by the most banal thing and I know it's because of my perimenopause.

How do I cope? I won't take hormones or birth control b/c those have side effects and I don't want to deal with side effects from meds that are supposed to help my side effects from the perimenopause. So, I do a LOT of walking, and take a lot of baths, and drink a lot of loose leaf decaf teas. I also eat a lot of dark chocolate and find that really helps my moods.
