Is water enough?

Wasn't overly warm today, think we hit 83*. Had 2 quarts of water with breakfast, along with 2 cups of coffee. First cup/quart of water was at 5:30 when I got up. Second cup/quart of water was at 7:30 with breakfast. Drank another quart of water during the afternoon. 1 beer with dinner. 2 quarts of water while I was on the treadmill. Another quart after I got off of it. Also had a quart of Gatorade. Feel so damn dehydrated...
