Right now I really don't. I never been drunk and I mainly only drink a lil at family parties. In college I might drink a little more, but for a more social thing and nothing crazy. I have the same concerns with alcoholism and plus I don't like the idea of people having the upper-hand on me while I'm drunk xD Plus I like the idea about being able to party and socialize without the need of a substance.
It's not too bad if you handle it responsibly, which is something I'm gonna try to do. I just really want to get wasted before I go to college so that way I know how much I can handle, how I act when I'm wasted, and come up with plans on how to limit/keep myself safe when I do drink in college.
