If by violently ill, you mean vomiting, gingerale and ginger snaps or saltines usually help. Get better soon, or check with a doctor. I had really intense gut pains, but since it only happened one in a while and would pass in a couple of hours, I never had it checked. I had a procedure done for something else, and they discovered the cause. And I thought it was just gas...
Get better soon please.
Or we'll get Pinkie to heal you her way.
Be healthy, wealthy and wise!
