Reflux is

I am not sure if this is very unique or not. For the last several years I have had an issue with reflux. Not so much heartburn, but if I drink or eat anything after two hours before going to sleep my reflux will cause me to cough for hours and my wife will not be able to sleep.

My doctor removed all my fluid from the band and that has cleared up the coughing, however I have gained lots of weight. It has been over a year since the band was drained, I wonder if I can have some fluid put back in
