So I figured I might add my own personal advice:
1) When playing poker, use a timer. Play 60 minutes round and force yourself to take a break
2) Always put music on when playing poker
3) Only play poker. No WoW or such at the same time
4) Always use your HUD. Always, always.
5) Watch at least one orbit before playing any second-level hands (hands such as QJs and so on)
6) Go to the gym before playing poker. Do heavy cardio.
7) Always have something to drink while playing poker. Preferably water.
