I too gained weight while on Zoloft. I was thin, so a few extra pounds didn't hurt. But, after six months, I hadn't changed my diet, nor my workout. I am extra careful not to eat too much and always exercising. Nevertheless, I gained 20lbs in 6months. That's more than I gained while pregnant. Today, I weigh as much as I did when I had my baby! Talk about depression!
Although my Dr. told me it isn't the Zoloft, I know differently. My body chemistry is completely whacked! I feel it, I know it!
Physically, I have experienced the following:
Lower Back Pain (I can't even get out of bed)
I contacted my Dr. and she suggested 25mg for 7 days to ween myself from the Zoloft. I did it, now I'm feeling Dizzy, and very light headed. When I go to back up in my vehicle, just the movement of looking over my shoulder to back up makes me dizzy! NICE! I have a call into my Dr. to find out what to do now!
