Trouble at 39hrs 30mins

I slept for the whole of my last 3hr break, but I guess there is such a thing as too much sleep because I could barely see when I woke up. I jumped straight into a 24-tabling session of cash but I couldn't focus on my cards at all and tables just kept on popping up in my face forcing me to move my eyes and brain, so I dealt with this problem by falling asleep half an hour in. I guess you'd class that as a challenge failure but I needed to fucking sleep. Have been one tabling 1c/2c to Celine Dion obv since I woke back up. Time to pass onto Keys, nearly over now, thankfully. This challenge was such a fun idea on paper. Oh well.
