Some people find that there's a great deal of enjoyment to be had in chemically forcing the release of emotional inhibitions, often if their daily routine requires a lot of stress and mundane activity.
This may be why I've never felt any real need to drink. I have relatively little stress in my life - I enjoy my job, I don't have people breathing down my neck, and I make it a point to avoid any responsibilities that are beyond my ability to cope with. This is partly because I despise being stressed out (it makes me all moody and irritable), and partly because I suffer from both high blood pressure and Tourette's Syndrome, both conditions that are aggravated by stress. I function best when calm and collected, thank you.
So with no stress to vent, there's not much point.
Besides, I've never had trouble with emotional release. If anything, I tend to share my emotions a little *too* freely - I'm rather sensitive, and usually have to fight to keep myself from showing it lest I be ridiculed or made a target. Anything that makes me *more* likely to blubber like a baby or get pissed off over something trivial is something I definitely don't need.
Then again, keeping my unmanly emotional-ness under wraps is part of why I'm shy to begin with, so...heck, maybe there's something to it all after all.
The idea is to not to go overboard like you're suggesting, and to be honest most social drinking doesn't. You shouldn't knock it unless you've tried it yourself, it makes you sound more judgmental than you're probably intending to be.
Oh, no, don't get me wrong - I'm not knocking drinking in and of itself. I was more questioning the mindset of people who enjoy getting sh*t-faced drunk, to the point where they black out, and then acting like it was the Best. Party. Ever. It seems counter-productive to go out to have fun and then not remember having had said fun the next morning.
Find some drinking buddies (round up some coworkers, or get with a DnD group, something) and have a little tailgate party.
I don't have any buddies to drink with.
All my friends (and my DnD group) are online, and I'm not allowed to socialize with anyone I know from work due to the nature of my job as a security guard (conflict of interest, and all that). Any friends I'd make would have to come from meeting them in places outside of home or work...and what with me being a geek, there aren't many such places that cater to my interests.
...although, there *are* a couple of cute girls I've seen working at Gamestop...
...hmm. I have some pondering to do.
For god's sake, just don't go to a bar by yourself. That's just expensive and depressing if you're socially anxious.
