I'm 26 and I was recently diagnosed with PMDD. Days leading up to my period, I get super tired, I get pain in my lower back, cramps, insomnia, breast tenderness, nausea, sometimes diarrhea, crazy mood swings, all day anxiety attacks...you name it. It settles down during my period but then gets bad again a few days after it stops. My doctor prescribed me 50mg of Zoloft and told me to take it for 10 days when my period starts. I was wondering if anyone else here takes zoloft for only 10 days out of the month and how does it affect you?
