Is there a way to ease my way into using less water without losing my energy. Daily I consume anywhere from 64-100oz of water but when I ride I usually do about 20oz per 10 miles. This means that on a 20 mile ride, I usually wind up using both my water bottles. I don't want to be forced into carrying a full camelback but I seem to require soo much water. Should I just start carrying 20oz for a 20 mile ride and see how it goes, or am I ok on the amount of water I'm drinking
