I have had the same problems. I have not have my band touched for almost four months now. I feel the tightness is right where it needs to be. A couple of months ago, I had this problem every night for about a week. Then it stopped. But then occasionally, it will happen again. In fact, it happened to me on July 4th. But I hadn't eaten anything for like 12 hours! And when it does happen, my lungs are in pain the next day. When I breath in, it will hurt in my chest and back. I haven't talked to my doctor about it, because it doesn't happen as much. But if it happened frequently, I would. I wouldn't be able to deal with it, if it happened nightly. Not to mention, the tightness of my band is always changing. One day, I am able to eat a good amount. Other days, it's hard keeping things down.
