Hi there,
And welcome to the forum.
I am thinking (can you smell the smoke???lol), you started zoloft eight years ago. As we get older, we do gain weight, and it is harder to lose. So your age could be a factor. I would take that into consideration. I am 51 and it is hard to keep the weight off. I really struggle, but I wont give up my ad at this time.
So talk to your doc and see what they say before you start weaning off. And if you do decide to wean off, please have your doc help you.
Keep posting, I am glad that you found us. There is a wonderful group of members here and this is a good place to come.
I hope that you have a good day today. Keep us posted on how things are going.
Hugs, Karen
