'How to quit caffeine'

One problem with this year's trip to Burning Man was that I wound up hooked on caffeine again. Now that I'm back in civilization, I'm trying to give it up but it's just so damnably alluring, especially in one of those offices where the soda machines dispense free (and delicious) soda pops. Thankfully, someone (I truly cannot remember who) forwarded me a link to a delightful comic that is already helping soothe the pain.
