I like hour long naps before a tourney. I also have the time for the game set aside and planned. When I start, I am planning on what my chip stack will be (playing the curve}. I find that by playing the curve and staying calm that I can usually do fairly well unless I get knocked out by a fish mine.I find meditating on my Victory is always EV+
Whether or not that spirit bomb manifests is another thing
Usually on my break I take some coffe and go to the toilet.
I always drink water too. Depends on the moment.
