Helena I also was hospitalized for severe dehydration and spent almost a month there with part of it in intensive care. I couldn't eat or drink which of course caused the p obelisk. My doctors prescribed Protonix and Sucralfate for the acid and stomach. They are a Godsend! Regular acid blockers didn't work for me and believe me I tried them all. I am able to eat anything except milk and sugar products as they make me nauseous. Now I don't regret having the sleeve!
