Hi, I've tried several anti-d's.......Zoloft, Paxil, Effexor, Wellbutrin...and now I'm on Prozac 20mg. I've been on it now 2 months and I absolutely LOVE it. Prozac has changed my life for the better and am now ME again and getting to know the undepressed ME is a fun journey. Some tips would be to start out very slowly, 5 mg for 1 week, the 10mg for 1 week, then 20mgs. I am staying at 20mgs. I did have side effects, all the usual, insomnia, fatigue, just a dopey feeling but they all went away after 3 weeks. The only side effect now is low sex drive, but I actually enjoy sex more now, just have difficulty finishing it off. good luck, hope this helps.
