Hi Patricia,
Welcome to the depression forum, I am so glad that you have joined us.
As for zoloft, I lost weight. But it gave me severe diarhea. So I went off of it because I was too thin anyway to be losing more weight. But there have been many people who have posted that they gained weight off of zoloft.
I am sure that some will post with their experiences.
Keep posting and know that we all care.
Hugs, Karen
