The upshot of all this was that I did nothing but wander about and watch other people play for about an hour and a half. I finally got a seat at a blackjack table and made $50 in an hour or so there. Then a bit more wandering about and I was called for $2/$4 Texas Hold 'Em game. I took my seat, posted my blind and folded to a raise in front of me. Before the next hand could be dealt, they started a new $4/$8 Hold 'Em game and called my name for that one. Since I prefer to play the $4/$8 game (it providing usually more predictable play while still being a low enough limit for inexperienced players to play), I picked up my chips and moved to that game.
I did reasonably well, making a $22 profit by the time I called it a night. Not as much as I'd like, but I recognized a couple of places where I made some mistakes so I hope to be able to close those leaks in the future. Also impacting my performance at the end was the close proximity of the smoking area to the table I was playing at. It didn't bother me at first, but later on someone in the bar area was smoking a clove cigarette and the fumes from that gave me a headache at about the same time that the composition of the players at the table was changing due to people leaving and new players joining. The combination drove me from the place.
On my way out, I developed a bizarre hunger. It was about 3:00 a.m., when I'm usually at work, and I don't typically get hungry at that time. Not one to combat my body on things like that, though, I stopped and grabbed fast food for the drive home. Once home, however, my hunger was not abated. So I grabbed another snack before heading to bed by about 5:30 a.m. I slept until noon when the noise from the guy fixing our furnace woke me up. I answered a bit of email while he worked, rolled over and went back to sleep until nearly 6:00 p.m.
So I'm thinking that nights out like that give me a good work-out, stimulating my hunger and driving me to sleep longer than I usually do.
