Have you been tested for sleep apnea? I was having problems with acid reflux, but went in for a sleep study because I was having a hard time staying awake during the day. It turned out the treatment for sleep apnea (a CPAP) also took care of the acid reflux in my case.

As far as food is concerned, get thee to a good dietician. With luck, your Dr. can recommend one. Be ready to have only one good meal a day and plan on essetially snacks for the other two. Learn to love green beans.

You are right to be feeling cranky.
