i'm torn

Twice this week, on back to back nights, I was out sampling Wellington's nightlife until 5 a.m.
This certainly isn't the first time I've been out on a town until the early hours, but I'm trying to decide how to feel about the fact that it's easy for me to lose track of the time and just keep going until the night is gone and I'm into the next day.
I know how I feel about the next day though - my brain may think it can stay up as late as it likes, but my body always has different ideas afterward.
