I've woken up drunk before. Well, it wasn't exactly drunk. It was more like you body is drunk, but your mind is sober. I could think straight (more or less, I was fucking tired) but when I tried to walk, I was stumbling and nearly falling over. But that was after the night I had minor alcohol poisoning.
I know what it's like only eating dunner, lol. It happens most times I drink. My stomach is always fucked after aq night of drinking. I rarely get any other parts of a hangover, but gut rot is something I can pretty much count on the next day.
