abdominal pain

[Biciclista]

Once upon a time, my DH had to work in New Orleans after the Katrina hurricane/flood, and my stomach started bothering me.
my dr put me on some antiacid stuff and it magically went away; so when he came home, I quit taking stuff.
I had a very obvious stressor going on at the time, him being in that horrible situation, working VERY long hours, including driving late at night, every night; so it all made sense, I was worried about him.
Now here I am having some of the same symptoms again. I WILL go to the dr and i'm sure she'll prescribe some of the same stuff again, but this time, I don't have a major stressor; and I'd like to know if anyone out there knows of anything else to do besides taking drugs.
it's a dull ache when my stomach is not real full (i ate 90 minutes ago and it's back) it's on the left side at navel height.
It doesn't keep me awake at night and i don't feel it when i'm riding.

anyone have any thoughts, remedies?
