Have you raised the head of your bed as discussed earlier?? You'll be very surprised and it also helps with sinus allergies by helping to keep the sinuses more clear when you sleep.
I quit chewing tobacco and sodas. I will have half a sprite and some lime Gin mostly every afternoon. But the heart burn and headaches are gone now. Prilosec works great but you must stay on it. B soda works instantly but too much trouble to carry around.
