I am sorry you have OCD. I have lived with my daughter who was diagnosed 10 years ago and it is not a picnic. That said, she took prozac at first and it was incredible. She then had side effects and has been on zoloft for a long time and it really does help her. The doses of the SSRI medications for ocd usually have to be more then that for depression. My tiny 17 year old is now on 250 mg daily. She is such an amazing person to fight like she does. The other piece of unsolicited info I will give you is that Cognitive behavioral therapy is invaluable. Have you heard of exposure and Response Prevention? Made a big difference to my daughter at one point, and may again. Good luck.
