I do not understand.

I was at the bar at 9:20, had five beers, then left after midnight.

I was still in control of myself, and could remember everything.

I still was in control of myself at 3 am, after two more "beers". WTF?

Why is it okay now, but not last Friday, or the Friday before that?

I know September is rough for me, but still, it shouldn't be like that.
