I've been using Heed for the last two years and am satisfied with it. Nuun made me bloat in an alarming fashion. I don't supplement with caffeine specifically, but I drink coffee in the morning and some of my Hammer Gels have caffeine. I carry a gel more as an emergency supply than a standard fueling strategy.

Yesterday's club ride had two stops: bakery and dairy. I had a doughnut at the first, but skipped the ice cream at the second. So there's another idea for you! :laugh:
