Drink your calories bud. Get an old 1.25L coke bottle and put in 200g of skim powder, then add 50g of Sustagen, then fill with water and shake. There's 1000 calories you can take in in about 2 hours and still feel ok, i.e. not wanna chuck it back up. I take in about 2 of these a day. Heaps of protein, minimal fat. I'd never get the calories otherwise. Cheers.
