Does this happen right before your period? I also wake up with night sweats, usually before my period. I noticed I don't sleep as well and have strange dreams. Maybe it has something to do with hormones. I'm 33 and not on the pill. It seems the older I get, the worse pms gets. I feel normal about one week a month. I get bad pms for 2 weeks, bleed 1 week, and that leaves one normal week. Damn hormones.
