Patient : Why does it seem I'm always dehydrated? I'm an avid runner. I try my best to drink tons of water (usually about 2-3 liters a day). During the day I'm fine. My urine (after I drink) is nearly clear. However, usually late at night and when I get up in the morning my urine is dark yellow and I'm extremely thirsty. There are even times when I wake up in the middle of the night with excessive thirst. It seems like I can never drink enough.
