I can only speak from my experience. I take Celexa & Welbutrin. I have taken both of them by themselves and they work so much better for me if I take them together. Welbutrin can help with weight loss. I do not think it is a substantial amount and it is NOT a diet drug, but one of the side effects can be weight loss. Everyone is different and will react differently. Give it some time, and see how your body reacts to the medication. Good luck & keep me posted.
