There was an occasion when I had two beers - it was similar to last night. I don't remember when that was, though. If it was anytime after June, then that's the last time I had a drink, otherwise it was May 29.
It's not the not remembering that's the problem as much as remembering is. Sometime it would be great to misbehave the way I tend to under the influence and simply not remember every humiliating detail. :)
