I had an ulcer that would flare up whenever i would drink coffee or eat spicy foods, i also had heartburn occasionally.
What cured it for me in a matter of a few days or maybe it was about 2 weeks was drinking Kefir everyday.
I would drink about 1 glass in the morning, and 1 at night while taking probiotic supplements. That cured my "ulcer" or whatever the problem was.
Hope this works and helps somebody else.
