I agree tht your esophosgus just sounds iritated. When I had a slip, I had days where nothing would stay down, I would even slime on water. Then I had days where I could eat and drink like a bandster should. I had heartburn and bad reflux and nighttime choking on reflux....but, not every night and day. It was often enough that I knew something was wrong, and went in for an Upper GI. Unfortunately, mine was severe enough to require a surgical fix.
My original surgeon was a quack and never placed it correctly. I am 1.5 years out now with my fixed band and doing well. It would be good for you to get a check up, but for now, I would just stay on liquids until you feel better.
