Thanks for your detailed reply. When my ENT doctor suggested I go on Prilosec (my symptom was hoarseness), I didn't because of fear of long term effects, most notably, dementia. If I had listened to him, perhaps my condition wouldn't have progressed to full blown Barrett's. Now I'm on 40 mg. pantaprazole daily. By taking Prilosec (omeprazole) 2X daily, you're taking the same 40 mg., which is available by prescription and should be covered by your health insurance. You might want to check into that.
I also ordered a full body wedge for my bed from Amazon. It's a foam wedge that goes under a mattress. One doctor told me it's really important to sleep with a wedge to help prevent reflux when you're sleeping. All the articles I've read say that pillows are not enough. I don't know how helpful it is, but my reflux when I sleep isn't very bad. In fact, I'm not very symptomatic at all, and since being on a low acid diet, my hoarseness has greatly lessened, and my most recent endoscopy, one year later, showed no sign of Barrett's Esophagus. I do try to finish eating 3 hours before bedtime, and my internist recommends intermittent fasting, which another expert called the latest fad!
My Bible for a GERD diet is Dr. Jonathan Aviv's book, "The Low Acid Diet." He's recently come out with a cookbook as well. Still, there's no caffeine, ergo no coffee, in his books!
