I think you are running around seeing too many doctors and then also getting in the mix and doctoring yourself by taking yourself off meds! Go back to the new PCP and tell him the WHOLE story of what you've been on and what/when you took yourself off and the weight gain thing and have him find you something that will help and not cause you to gain weight and give him back the rest of the Meridia and lose the rest of the weight the healthy way! You want mental health? You aren't going to get it mucking about with the meds on your own like you're doing.
