Fluoxetine
"I have suffered from PMS or PMDD most of my life. It was such a horrible experience for me that I would have crying spells; have arguments with people; I would shut down at work or would have to take at least 1 day off during the week of my period. I tried several different birth controls but they didn't work so I finally asked for Prozac after hearing it did wonders for a co worker. Ive been on it one month; my cycle came on today (TMI) and I still feel great!  I can't believe it!!"
