Just got a call at 2:10 AM from a friend of mine—a usually stolid and reserved friend—who was bouncing off the ceiling giddy. The purported reason? Red Bull and vodka, mixed in with his usual quota of alcohol for the evening. Guy’s state was altered enough that I wondered if someone had spiked him with something harder and less legal.

So I’m going to have to give this a shot sometime, without the alcohol. Working theory: mixed in with my usual estimated daily intake of 18 mg of nicotine and 1,890 mg of caffeine, the only effect I’ll see is a lighter wallet. Either that, or my head will explode.
