Yes, I had the same problem and found out it was that my band slipped! I was coughing at night also. It had been going on for quite some time. so now I am waiting to see what the next move is. I just move and the doctor said he can't put another band in. Bit after reading these blogs I think i need to find a new doctor. You might just be too tight also. Have some saline removed, that might help! I had my band put in in March of 2006 and lost 150lbs and since they took all my saline out I have gained 20 back!! Very scary! Good Luck to you but try to have some Fluid removed first!
