If I'm thinking correctly I think the carafate caused bad constipation and stomach pain which lead me to overdoing it with the Advil and the Aleve and my GI doctor said those caused the ulcers.

I had the heartburn and stomach pain to begin with thats why I went to the GI doctor. I had been dealing with chronic constipation for years until my physical therapist fixed it. But it got unbearable after the Carafate.
