...I'm ten years older.
Otherwise, the likely scenario would have been:
** I would have had a terrible weekend.
** I would have probably called in sick today: my day at home would have been as terrible as the weekend would have been, anxiously turning over Friday's events in my mind and wondering whether I'd allowed myself - or rather my drinking - to get completely out of hand, and my behaviour with it.
** I wouldn't have been a good-natured drunk on Friday night.
** I would be looking for ways to blame other people for how drunk I got, rather than taking the responsibility myself.
** I would be feeling pretty low right now, as opposed to thinking about the good-humoured conversation I had today with my colleagues about Friday night.
** I wouldn't be feeling as good as I am about the arty things done in the group at work today, and how well they've turned out.
Yes indeed, thank goodness.
