My doctor told me I was dehydrated based on a urine sample . So today I drank tons ... Didn't even know you could drink to much. This morning in the space of two hours I had at least two liters. Then I had a evian 750ml bottle then a tea and a coffee and this evening two pints of water. This sounds like the amount that it is fro water intoxication. I have a bad head ache too. I feel so stupid
