It's not that hard. Coke Zero was my weapon of choice I believe.

I did lose about 5 buyins, but I only played 8k hands in 24 hours. He'll play like 18k. And I was playing 6m, he's playing FR, the former is going to be inherently swingier.

Mostly the hardest part is the boredom. I used fark.com to combat that.
