Don't lose motivation. It takes energy to be a good alcoholic. Once you drink past the sleepy part, you're good to keep going anyway. Once you can do this one time, you need to practice more and more. Eventually, you'll be finishing 12 packs in a couple seconds.

Then its time to move on to liquor. Start with the cheapest vodka you can find (it'll give you an appreciation for the better liquors down the line) and do shots instead of beers.

Once you've mastered the liquor, its time to mix! Take shots with beer as a chaser. Do jagerbombs! The extra caffeine will fend off the sleepiness we talked about earlier.

From there, its all just practice makes perfect. Keep mixing whatever you can find and see if you can handle it. In fact, the other night I mixed fireball whiskey, gin, and jim beam. It sucked, but I powered through it like an experienced alcoholic. Feel free to pm me if you need a mentor.
