I think tapering off caffeine is a lot more gentle than going cold turkey. And if you are in a hurry for whatever reason, plan to have one ~50mg dose on day three or four when the headache gets distractingly bad. You can use Tylenol Ultra Relief or Excedrin Migraine if you don't want to deal with coffee or soda. That should get you over the hump with minimal disruption.
