THANKS to y'all (I live in the South now) for your responses and suggestions!
Canklecat, thanks for the tips... I feel your pain! I went flying off my bike about six months ago and broke my left clavicle.
Machka, I didn't mean to give the impression that I chug a full bottle. I stop at one of several rest stops along my usual route and, over the course of five to seven minutes, slowly drink the contents of my water bottle, refill at a water fountain and head out. Today, however, I started to take sips while in the saddle. I can see it gets easier and, I drink less water while taking less time for my stops.
