premenstrual dysphoric disorde
"I was prescribed Fluoxetine 20mg for 2 weeks of the month and it has changed my life. The first week I had some nasty side effects - kept waking at night, nightmares, nausea, generally spaced out and tired - but also some more welcome ones - loss of appetite and really wanted to exercise. I barely noticed my period coming that first month. For the first time in as long as I could remember I didn't hate everyone or want to cry, and I was able to have normal social encounters without complete paranoia setting in! It was like I had got my old self back. 9 months in now, I am quite happily still taking them. Definitely worth trying if you do get really bad PMS."
