The reason your motor skills are adequate is that you have only had 4 drinks.
I rarely get blitzed, only 4 times so far (I'm 17). My latest was about a month and a half ago in which I drank 10 beers. The funnest part of getting blitzed is when you are told stories about what you were doing the night before. I saw a picture of me on my wood floor getting licked nonstop by my dog, and a pic of me with a trashcan on my head, and various other things! Real fun, but if you get hammered more than once every couple months I don't think it is as fun, because the feeling isn't as memorable.
As for taste, I dispise beer but it is cheap. My favorite is rum. I love rum and coke. One of my fondest memories was a night when I stayed up late, had a glass or two (I didn't get drunk, just had two drinks) of rum and coke, a cigar, and watched Crimson Tide.
