My Depakote was changed to Zonisimide. Made a big difference. Maxy
Agree with above, what you need to do is either change medication or see a specialist who can help you to change your diet. It's not easy, I gained a lot of weight on Paxil despite not eating any more than I ever did and exercising a lot.
Alt to meds. Try a Naturapathic Dr. And or a Holistic Dr.
As for your antidepressant, there are others to try as well. I would not try two new meds at the same time so you can see which one is the weight gaining problem. It's certainly possible too that this combo of med played havoc on the weight. I know feling well is vital but I also now feeling good about yourself is important. It is for me. Why not feel good in all areas if we can help it. Wishing you the best.
Some meds I have taken have literally made me hungry all the time. Even so, I didn't give in as hard as it was and still gained weight. I personally gained 25 pounds on Depokote. I should have stopped it before it got out of control.
There are plenty of other meds out there to try. There are weight neutral meds. Lamical seems to be well spoken about, you just need to be aware of the Lamical "rash". I would talk to your dr and say you would like to try a weight neutral med. Abilify is highly spoken of too. Everyone is different so what makes one gain weight, have side effects, works or doesn't work, you just don't know until you try.
