The HN news hoardes will probably be here soon to chastise me for even remotely giving health advice over the internet but when I had an ulcer I found out that in Japan doctors will actually prescribe powdered Glutamine (its just an amino acid - common building block of protein - so pretty damn safe) for ulcers and many things that involve the lining of the GI tract. Apparently the walls can directly use glutamine to help repair themselves. Seems to help me a lot and I just regularly started taking small amounts of it daily since I sometimes love eating an exorbitant amount of spicy food and that can be pretty harsh on your insides.
