I have several levels of drunkenness.

-The first is simply a biological awareness of the fact the there is alcohol in my system.
-Next comes light buzz and moderate buzz. Through those three I'm still coherent, no less coordinated than usual (not saying much) and I'm still below the legal limit for driving.
-Heavy buzz is the point at which I start to think less before talking or acting, I can no longer drive legally (I could do it coherently enough that I would in a life/death scenario, but despite my confidence I wouldn't try otherwise,) I may start to lose balance but will be able to recover, and my skill at playing Beiruit is at its peak. At this point I've lost my ability to feel cold, and pain tolerance increases dramatically. I can still pass a sobriety test if my arthritic knee doesn't give out, but a breathalyzer would reveal the truth because I wouldn't remember how to trick it.
-From buzz, we move on to drunk. I'm staring to lose balance, coordination suffers, and my stomach is going to feel a bit off the next morning. My reaction time is slowed significantly and if I turn my head or move my eyes quickly I get dizzy. I would be best off staying away from particularly sharp objects and if I'm playing lawn darts a wider space than usual should be cleared in front of me.
-The last stage is crunk. When crunk, I slur my words, cannot walk in a straight line, words go from ideas to speech without the rational part of the brain interfering, and I won't remember anything the next day that I don't focus on for a few seconds.
-Past crunk is the blackout. I only did this once, after chugging half a liter of absinth (don't ever do this.) I woke up the next morning with the only memories of the previous night being falling down the stairs outside, falling down the stairs inside, staring up at the bottom of the stairs inside, playing kings with a glass of straight absinth instead of beer, puking over the fence, and checking with my brother to make sure I had given him my keys. I only achieved this state once and don't plan to again. It was also the only time I puked from drinking other than the time I inhaled grain alcohol.

Considering that it's only 80 proof, I think you're right. The additional effect feels like huge amounts of raw nutmeg, but much less intense
