Unless I'm mistaken, you're not supposed to discontinue taking Prozak without your doctor's supervision... discontinuing it suddenly can create a chemical imbalance. Did you discuss this with your doctor? I feel quite sure (don't have the book in front of me) that Dr. Atkins does not advocate stopping the medications w/o your doctor's approval, he only states that they may make your weight loss slower. This is not a reason to discontinue the medication if you really need them!
