Don't decide now. Wait until Sunday and then decide based on how you feel. I always have best results when I am rested and psyched to play some poker. When the time comes near you judge if it is better to rest a little and play big BTC later or squeeze a couple hours of poker in out tournament and call it an early night.

Big BTC starts at 23:00 so I have to be well rested and not working next morning to enter it with clear mind. If I am tired I just force it too much.
