I struggle with this too....my current med isn't packing the weight on yet though. The only advise I have is probably something you already know and that is not to drink your calories (unless it's healthful drinks) ive never been a soda drinker but a few times when on meds I began drinking them and the weight piled on fast. Lots of fruits, veggies and nutritional stuff, no simple or low simple carbs, limited complex carbs. Basic nutrition stuff. I'm going to ask to see a nutritionist if my meds start bad weight gain. Do you have access to a nutritionist?
