I've been on zoloft for about a month and a half now and I've now gained about 10 lbs!! This is stressing me out more than ever before, especially since I have a borderline eating disorder and obsession with my weight. I want to say it's the zoloft, for as little as I eat I STILL gain weight. I'm getting more and more desperate, and I see this taking a turn for the worst if it doesnt stop (e.g. not eating, purging etc.) Has anyone else experienced this weight gain, and is there any other med that either counteracts this weight gain or is a better substitute. I've been on effexor and lexapro before, both which i lost weight on. And info would be greatly appreciated!
