Are you allowed to take prilosec? If pepto is what you are allowed, do you know they now have chewable tablets AND caplets (not chewable)? Those might help.
You also might see if zantac, sold as Acid Reducer at WallyWorld) would help. If it is an acid problem, maybe a teaspoon of baking soda in a glass of water would help
I hope you feel better soon.
