lucydear, I was on Prozac for 4 months and gained 40lbs!! I was reduced to wearing yoga pants 24/7 because they were the only thing that fit!! I LOVED Prozac, never felt better, but I could not bear to see the 42lbs. I had lost and was maintaining, come back. If your doctor "doesn't know what to tell you", go see a specialist. I had been on all different anti depressant anti anxiety meds since I was 13 (I'm now 25) prescribed by my family doctor and it was always a medication rollercoaster. After going to see a specialist I was put on a mood stabilizer and, Wah laa!! Perfection!!Maybe get a referral from your doctor or use Google to find a specialist in the area if your doctor isn't helping. I am now medication free for the first time since I was 13 and I understand your stuggle, but I'm STILL trying to lose this Prozac weight!!! Good luck!!!
