If you literally can't tolerate anything you put in your stomach, something is wrong. Not even water stays down without icky feelings? Have your surgeon prescribe you an anti-nausea medication. It's important you get in as many nutrients as your healing sleeve will allow. As for the SK Gladiator, yes certain combos taste awful. You have to find a fruit combo that works with it. A word of caution, though, the fruit adds a lot of calories. It's fine right now, since you hardly eat anything. Later on, however, you'll need to get off that crutch. I liked the Gladiator chocolate with banana and peanut butter. I don't care for the whey taste either, but this combo was actually very good. I love it. Just wi**** wasn't so many calories so I could have it now. =)
Keep trying. Get the medicine, keep trying different things. It will get better.
