Twenty pounds is a lot to lose from this!! I don't know what half the meds are that you are taking, but I have taken the Wellbutrin, Lamictal and Seroquel...none of which you should drink with! Have you read the side effects of some of these drugs? You definately need to talk with your doctor about this and consider not drinking. Drinking is not good for anyone (and I do like to drink)let alone someone taking as many meds as you.
