I just had this problem and have went back to get an unfill and it has made a world of difference...I was having trouble getting water down comfortably and it is so nice to take a drink of water and have it go completely down! I have lost 35 pounds since my surgery 11/27/07 and i already feel like a new woman!! If you are having trouble, talk to your doc and go for the unfill....just a little bit will make a difference! I want to be able to eat my grilled chicken and veggies when we go out(at least part of it anyway) with out having to throw up! Hope this helps!
