I have the EXACT problem. SOme days I am able to eat certain things and other days it comes up. Why??? Someone told me that mucus can rest on the band and that will cause us to slime up or throw up the food. I am VERY frustrated at this very moment b/c I am having this problem for the last 2 days. I was able to eat very good this past Sunday. Yesterday I wasn't able to eat anything at all, just some liquids. Today (Tues) I wasn't able to hold any liquids down until around noon and the only thing I can get down is some warm water. It's at least staying down so far so I don't get dehydrated. If l can't get that to work then I have to go in and get some of my fill taken out. The strange thing is that although I did have a very tight fill it was 8 months ago!! I have heard that the band can tighten up sometimes so maybe this is what I am experiencing. I'm just so hungry and wish I could eat something right now but the nurse at my lapband doctor told me to wait and see if the water stays down. If that does then I am to try some soup this evening. Hopefully I can get it to stay down and maybe soup for dinner tonight. IM STARVING. I HAVEN'T EATEN IN A DAY AND A HALF!
