My periods have been in and off for a while. I'm nearly 45. For the past couple of months I've been sweating and sweating through the night and have to change the bedsheets each time. Now I feel like I'm stoned, it feels like the most severe PMT and I sometimes wake up suicidal but this wears off, leaving me in a fug all day where I can barely function. What do you think...peri-menopause?
