My husband does the same thing...He has been diagnosed with sleep apnea and GERD. He was put on prilosec and a C-PAP , but we lost my insurance and now he uses OTC remedies and they are of no help.
I hope your husband gets better it really is hard to watch and I am sure harder for them to endure

. Not to mention dangerous.
Will keep you in out prayers and let us know how it goes.
