I have had my band going on three years now. I haven't had an adjustment in over a year, and this started with me about six months ago. Coughing all night, maybe about two or the times per month. Got so bad finally that I wound up in the hospital last week with pneumonia. I came up with a theory. I'm no doctor but I'm still testing it. Everyone that is having this happen, do you sleep on your stomach? I did constantly and I think the pressure on the band pushes food/liquid back up while you sleep. Been trying to sleep on my side and back the last few nights. So far so good.
