In a word, No.

Like big john above, on a hot day I'll sweat about twice as fast as my body can absorb what I'm drinking. Now that the daily highs are below 90 F, over a day's ride I can almost balance water in/water out, and only by forcing myself to drink.

When it gets cold, my kidneys take care of any excess I drink. Maybe I could force myself to drink a gallon when it doesn't get over 60 F, but since it doesn't feel right, I don't.
