I don't believe so.
More specifically I have a case of dull aches in my upper stomach that flare up a few minutes after I eat something. When I have a "movement" I feel relief. My roommate thinks I have an ulcer which he has said:
a) eat more fruits and veggies (which I have been doing)
b) No more alcohol
c) no smoking
d) run run run.
I haven't drank in weeks, I haven't smoked since last March, I eat a moderate amount of greens and fruit, and I haven't found time to do jack sh*t for exercise since Winter Break.
