Humblestudent, I do exactly what you were talking about. I drink weaker drinks...and then drink more of them. I blackout from early in the night and can still be completely functioning but missing hours of memory the next day. That makes me paranoid and scared to talk to the people I've been socialising with. I also read far too much into what people say to me when I'm drinking. Did they say that because they think I'm drunk? etc etc.
