I've had the same exact issues, but decided not to get any fluid removed. I noticed specifically what I was eating was contributing to my band becoming inflamed (alcohol seemed to contribute a lot, ugh). But I know exactly how you feel and although I was able to get back to normal by changing my diet a bit, that feeling of sickness and reflux is one of the most uncomfortable things I have ever experienced. I would say try to eat more filling foods, such as oatmeal, and maybe incorporate small healthy snacks throughout the day (like fruits and vegetables) to keep that feeling of "full." I also understand your paranoia to get a fill and my advice is try to tweak your diet before getting a fill. Keep a diary of your foods, too, if you're not doing that. I hope you are able to keep going strong without a fill (or if you get a fill, that terrible reflux doesn't return!!). Try not to get discouraged, you've come so far!
all the best!
