I could drink them BEFORE the surgery. Thought they tasted horrible, but I could do it. Post surgery, they go through me so fast...it's like lightning. For hours. The only thing which seems to not is meat and pineapple (I know...but it's the only thing which makes me poop regularly). I've tried every kind and brand. Whey, soy, all veggie, bone...the sports drink kind (still whey)...nothing works. I cannot be absorbing what I need if they are blazing through me like that. HELP!
