64oz? That's it? Must be nice! You're supposed to drink half your body weight in ounces so that used to be over a gallon for me... Plus, during Winter, I like two big mugs of coffee every day so I have to overcome that too! Oh well...
With all that it probably sounds like I could get into trouble when I get stuck in the ridiculous traffic around here, but I keep a "trucker's helper" in the car along with a towel. A quick pull-over to the side and I'm soon back into the traffic! ?
