it really depends of what am i playing...
if i had a tough decision near of the break, than i would bring the hand for a quick study.
in a mid~late stages of the tournament, if i didn't do that until the break, i will map the players of my table, if i just change table before the break, i will certainly do this.
if i am doing great, have everyone map and didn't remember if i want to solve something, then i will drink something, go to the bathroom, talk to my wife, play with my kids a little...
that's it.
