I have a medical issue I'm hoping I can self-medicate with and not have to go to a doctor and get prescribed pills to treat.

When I was in the military, I had my gall bladder removed. It turned out that I actually didn't need my gall bladder removed because the pain that caused me to go to the doctor in the first place persisted after its removal. Since it was during the military there's nothing I can do about this misdiagnosis and now not having a gall bladder has led to another inconvenience: If I'm hungry for too long I get really bad stomach cramps and/or "the runs". I've tried to prevent this by self-medicating with ginger ale or Tums but those don't seem to work; the only thing that does seem to work consistently is drinking liquor before I eat if I've been hungry for an extended period of time.

I don't want to have to drink in order to not get these stomach aches, and I have no clue why drinking liquor would work. Is there something else I could use that would have the same calming effect on my stomach?
