"I am pre-op and have been replacing two meals a day with protein powders. I have tried some from Bariatric Advantage and Unjury, but this is the best tasting. The first ones I didn't have to "force" down. Vanilla mixed with Orange Crystal Light is great. I've also been using some sugar free syrups. The chocolate powder with german chocolate cake syrup is fantastic too. Cheaper and better tasting. What is wrong with that?"
