Hi...I wasn't on Zoloft but Lexapro...I think all SSRI's are just about the same. I was really glad to put on some weight after starting it as I was so depressed I wasn't eating and became way too thin. Until...along came 22 pounds. I stopped the drug in October and have not yet lost a pound...if anything I've gained a couple of more. The brain zaps? Have had them every single day since I stopped taking the drug so please talk to your doctor and wean slowy. I pretty much cut the pill in half for a couple of months then just stopped at 2.5mgs. Bad idea. I would really like to know about the weight-thing too. Maybe it is just age, and it's harder to take off when you become an 'old broad' like I am!
