For the last few years I have been in hell,1- 2.5 weeks out of the month my entire body chemistry changes including but not limited to temp, anxiety, mood changes, night sweats, dizziness, weight gain and loss, appetite changes, vaginal dryness, wetness, cramping, flutters in my abdomen, etc. I have been in cymbalta for a few months with Xanax. But it's not working and these medicines are horrible. Currently I have to smoke mm to function without going insane during these periods. I have endometriosis and pcos that I had a lap surgery for last year. I am desperate I've tried several hormone methods to treat both and I've tried ssri's. I'm not sure where to go but it's driving me insane. Any suggestions to what it might be or what could help?
