We all respond differently to these types of meds.
I took
Zoloft for several years,
with no side effects, and certainly no weight gain. If one person out of thousands experiences a side effect from the drug, they have to list it. It is a safe drug, and if you should start to feel any of the side effects, just contact your doctor and never stop taking it abruptly, always work closely with your doctor where your meds are concerned.
I think an antidepressant will help you.
