I drank about half a water bottle too fast and am experiencing an upper stomach cramp for hours now. what can i do for relief?

It is not due.. wate: By now it should be gone! If the pain persists, you may have something else going on in your tummy. Get a medical check up if your pain persists or is getting worse.

Water bottle: It is very unlikely that a half water bottle should give you a stomach cramp. If it has gone by now - great! If not please have someone take you to the nearest Emergency facility.

It's not the water: There is something else going on that is causing your cramping. See your doc ASAP and get a good history and physical to find out what's going on.
