Alcoholism is a disease. While there is no cure, I have found this to be an effective treatment:
1. Avoid Jager shots. The same goes for tequila, Everclear, or huffing paint thinner in a back alley.
2. Order club-soda backs when drinking whiskey. Not only will a few pints over the course of an evening save you a world of hurt the next day, the bubbles tickle delightfully when vomited through the nostrils.
3. Knock back a Red Bull when you start to flag. You want to feel chipper as the evening progresses and the appearance of other bar patrons starts to improve. Stronger energy supplements, especially those of South American origin, are to be eschewed as they can lead to paranoia, erectile dysfunction, and sophmoric stupidity one tries to pass off as insightful wit.
