I drank a gallon of water in 1-2 hours time. this was over 24 hours ago. was the gallon to much? raising anxiety levels over fear... drank 20oz today

Not dangerous: Generally, one should drink not more than one liter per hour, as the kidneys can only eliminate about 1/2 liter per hour. But a young healthy man would have to drink gallons of water to get in serious trouble, called hyponatremia (when sodium levels in the blood get too low). Dizziness, headache, nausea, and diarrhea are common symptoms of "water intoxication". Try CBT therapy for your anxiety.
