So it's my third day without flour or sugar ... this is a crazy idea for a cyclist, not recommended during the biking season.

But it's below zero here in Wyoming today, and I've done exactly two studded-tire outdoor rides since the snow descended in December. Besides a long X-C ski here and there, I haven't sweated for more than two straight hours since September. Lots of indoor training, but I really need to stop the madness of my sugar addiction, and, Ullrich-like, drop 20-30 pounds during my personal "spring training" boot camp. My excesses have led to excess ballast that slows me down, especially on the hills.

Anybody else doing this sort of regimen? Do the cravings really go away?
