I have the larger band, and I have not had a fill since August. I've been feeling just fine until lately. I've started getting sick after many meals, which has never happened to me before. Last night I was up in the middle of the night with some pain, and I threw up six times after a meal of salmon and steamed broccoli. That has NEVER happened. It could be just a bug, but I'm worried about a possible slip. I'm trying to be optimistic, because I had a very hard time getting restriction with my band, and was so happy to finally have restriction since August. I've been banded 15 months and have lost 85 pounds. I have 70 pounds to go. I don't want an unfill, but I don't want to ignore a serious problem either. If you've experienced a slip, I'd like to know what that felt like. Thanks.
