Have you ever drank so much water your stomach ached, you felt you couldn't breathe, and your kidneys and head started to ache?
Water intoxication feels bad, but it isn't damaging unless you drink so much your brain expands. But 5-6 liter in 2 hours should be safe.

If you want to make it extra hard on your stomach, drink iced water. If you want to start of easy, drink hand temperature water.

I hope you can quit the tylenol.
