Calculate Your BAC Before You Get Behind the Wheel

Tis the season for holiday parties, which means you'll likely be exhibiting some poor judgment at some point like drinking bourbon way too fast at your company holiday party, biting cheeks or trying to use "Do you know you look very elegant?" as a pick-up line. Any of the aforementioned behavior should tip off your friends that you probably are not the best choice of wheelman to get you and yours back home in one piece.

However, convincing them, or yourself, of that fact can be a chore - particularly if you've just kicked everyone's ass at Dave & Buster's NASCAR game. That's where B4U Drink's Blood Alcohol Concentration projection tool comes in handy.

The website is designed with mobile devices in mind and is easy to use.

1. Navigate to the site: http://www.b4udrink.mobi. Pro tip: do that now while you're sober and can actually type effectively into your iPhone.
2. Click through the introduction & Terms of Service
3. Enter your gender and weight
4. Enter the quantity and type of drinks you consumed (or plan to consume)
5. Enter the duration of your bender
6. Start dialing the cab company as you read your score

Be safe, Houston. When in doubt, cab it out. That way you have to cab it home.
