43 means go to bed before 2 am

I am noticing an enormous lack of energy after a dinner and a couple drinks. If one attempts to then go out around 11, there is now an expectation of a price to be paid. Especially if one stays out with 20-30 year olds. While the wife and I looked better than the rest of the group, once home I tried to not move for 24 hours. Difficult at best with a toddler.
