Try changing your diet, eating smaller portions, elevate yourself while you sleep, and try Meadow Sweet, Lemon Balm, or Peppermint for herbal remedies. I also hear that meditation and Tai Chi may help.
i take both metoclopramide (reglan) and zantac for this...had it really bad when i was younger, so i know how shitty it seems. hope things get better for you!
