I had this problem yesterday, I could not drink more than 40oz of water, I was hiccuping and I felt like my stomach was in my throat, had a kicked in the gut feeling and my left rib had a stitch in it and then heartburn. I called my doctor yesterday (on Saturday), they had me go into the office, they came in and took fluid out of my band, it was filled to tightly. Call your doctor, that's what they get paid the big money for. it is better to be safe than sorry.
