Hi, I am almost three weeks out from a bypass and started experiencing the feeling of liquid coming back up into my throat after drinking, similar to reflux. I had a couple days where I vomited and I think that is be ause I was putting too much in my stomach too fast. (Only took 3 sips to do it). I saw my surgeon yesterday and he explained that there is still swelling inside the stomach and that I need to take the drinking a little slower, but to keep with it. I may get some IV fluids for it, but I just keep woking on sipping fluids to get my liquids in. I have to remind myself it is a marathon, not a sprint. Hang in there!
