It sounds to me that your band is too full. I have had the same situation happen to me, but it was due to major stress in my life. With stress you retain water, that water retention will put pressure on the outer side of the band and treat it like you would have just gotten a fill, but an over fill. I have unfortunately also had a Dr. (Don't Dr. shop, this may happen to you) over fill me once as well and it is the same as I call it "Jimmy Hendrixing" effects. There is nothing like being woken up in the middle of a deep sleep choking on your own vomit while trying to breathe at the same time. It's horrible and not good for your body and band. My Dr. is located in CA and I was unable to make the trip down there for 3 months. (With the Dr. that overfilled me that one time I am really Leary about going to any other Dr.) My Dr. felt my port and stomach, said my band was really tight, removed 1cc and I have been perfect ever since. This may not be the issue, but it's worth looking into it. Good Luck!!
