I went through the same thing you did. Yes you should allow your self at least half the allowed time before you make any kind of decision, clear your head, and if at all fails you dont know what to do, fold and wait till you are for sure. Also try playing some smaller SnG's, right there is a good hour of play time to where you can work stuff out, get a feel for the game. What I am doing right now is bonus whoring, and just worry about clearing the bonus and not making a (MONEY MAKER) a lot of money. Even though we play poker to make money sometimes you need practice and cant play the game all the time!
