H2O

I don't know what it is, but I can't get through a day with out water.  I don't mean drinking it either, though I do drink about 2 liters or so a day.  What I mean is that I can't get through the day with out having some part of my body in contact with water.  About half a dozen times or so a day I have to go to the bathroom and splash my face and wet my hair and just feel it.  I can't explain it.  I just need it.
