How would you know if you had an ulcer?

That is a tough one. I had mild ulcers after I went off antibiotics. For me, if I drank anything really acidic, a glass of red wine or coffee (for me) would give me pretty bad stomach pain. Also it was worse after eating but not too bad if I stuck with mostly bland foods. I did the high fat diet, avoided coffee etc for 2-3 weeks and then I was fine. Didn't go back to too many acidic foods for 2 months or so and then after that it was gravy.

I hope you get some relief soon missy! The first few months of treatment can definitely be the hardest.
