Hi, I have been taking 300mg of Wellbutrin for a number of years and it has been OK, but still need to be more motivated. Just lost my wife of 37 years to cancer. I went to my doc to talk and she thinks that taking 150 mg of Wellbutrin and 50 mg of Prestig will be better. I am really concerned about side effects. To date no side effects. I really don't want to be taking a lot of meds.
