Maggie,
This same thing is now happening to me. I had my band almost 5 yrs ago. Never had acid reflux or any problems like that. But, now I can't sleep - I wake up with the same problem bile coming up and also thru my nose. Sorry, really gross but true. Did removing some of the fill work for you?
I have lost all of my weight and cannot believe I am just now having this kind of problem.
