My longest session seems like another lifetime ago it's been so long. I used to play a lot back when I first started playing god missing being young and having so much extra energy lol. Anyway my long session was likely easily 15+ hours double tabling full-ring 50nl on
pokerstars. Yes as you can imagine I was exhausted when I finally logged off. Ironically though even though I was completely exhausted and drained it still took me over an hour to fall asleep when I went and laid down. My mind just didn't and wouldn't shut right off like my body was ready too. Just kept replaying and going over the big
hands, pots, loses and wins.
Fwiw finished up a few hundred if I remember correctly. Gave back $100 or so the last hour and 30 mins making pretty questionable calls and decisions. Not my finest moments lol. Competition back then was so soft didn't much matter much.
Cheers!!!
