The AWOL Machine (Alcohol With Out Liquid™), created by Dominic Simler, is based on the premise that "by mixing spirits with pressurized oxygen, a cloudy alcohol vapor is created which then can be inhaled." So, you get all the kick, but don't get a hangover. And ingest no carbs.
We never had a problem with those, actually. We just wish someone would invent something that stopped us being pompous, lachrymose, and just plain silly when we're pissed.
