I don't even need to be drinking, but sometimes I'll fat finger it a few times and get frustrated. The only way I can get logged in is to type really really fast.
Yeah, I find speed is important too. The quicker you can type it, the easier it is to recall. Another thing, if I slow down I notice i'm sort of humming parts of the pattern in my head, as if each character held a sort of audible weight that indicates where my fingers should go next... again, kind of like playing an instrument. Yet I can't play anything. Weird.
I've been wondering for a while where the boundary for being diagnosed with synaesthesia is - nearly everyone I know has some sort of synaesthesia, even if it's only associating numbers with colors. Yet, it's no where near the viewing-numbers-as-landscapes of Daniel Tammet's Born on a Blue Day or Nabokov's gift with words.
I suspect almost everyone has a little synaesthesia, just like almost everyone has a little depression, a little anxiety, a little Borderline Personality, a little schizophrenia...
I guess it's only worth giving your mental quirks a name if, say, they're 2σ above norm. I dunno, ask your doctor (or statistician :P).
