I have suspected PMDD and after being prescribed this pill I experienced a normal period for the first time in my life with no crying or rage and no convincing myself that everyone secretly hates me and that I should just isolate myself. If you forget to take them (especially at the beginning of the pack) those symptoms will return to a moderate degree however. My performance in college and my interpersonal relationships have improved since going on the pill. Is also fairly cheap, I get it from student health services for ~$10 a month.
