I'm normal too when I'm drunk, you can ask me the capital of Brunei and I will still know it ( Bandar Seri Begawan ), I remember all things I've done afterwards and I don't act foolish while I'm "sober" ...
I went to a home-party last year, I got so drunk that even after two days I felt dizzy ( damn Menaito song ).
I slept there and didn't tell my family about it, so they almost called the police, I showed up the day after, hahahahah, my mom forgave me :duh: she cried and told me never to do it again, after an OK, it was like nothing happened ... Of course I went straight to bed ( as I said still dizzy and shaking ) and took an 8 hour nap.
