I've had reflux for a few years now and I've been taking 40 mg Protonix mostly to control it, and it did for the most part, but the burning always woke me up in the mornings and my sleep/rest time suffered. I discovered recently that drinking a few ounces of milk before go to sleep helps a great deal, eliminating about 95% of that burning sensation. Now I can sleep in more often than I have for years. I hope this helps you.
I'm thinking about trying to get off the meds altogether by taking the ACV.
