I lost 110 pounds in one month in 2009, and used several medications. I'm up 50 pounds now. To add to what was posted to increase the appetite and weight....caffeine, wine..probably not a good idea, decadron..a corticosteroid, anabolic steroids, human growth hormones, b12, protein drinks, snacks, reduce exercise, supplement like yohimbe bark extract, smaller, frequent meals....See the doctors before trying anything, and several require prescriptions.
