I too have stopped invega as of yesterday. I did some research and it seems that if you get your prolactin levels down it will become possible to lose weight, but you still have to stick to diet and exercise. It probably won't just come off on its own. But the high prolactin is what caused the weight gain for me and made it impossible to lose weight. I'm hoping that if my prolactin goes down and I stick to low carb pretty consistently I will lose the weight. I doubt I will lose all 70 pounds I gained but I'll be happy if I can lose 25 - 30.
