Or is it just that I'm a total fish?

All week I have been fine Monday through Friday playing consistently good poker and winning. Then Saturday comes along and it seems like I can't hit anything, and go through everything I won this week in about two hours. Totally tilted right now and I'm shutting my computer down. Last straw was getting my QQ cracked to A7o on a rivered ace after a preflop 4xBB raise, hard bet on flop and turn and the guy called an all in before he saw the river with just a pair of 7's. That made me explode.

Plus - raises preflop (even 5-8xBB) were still getting called by 3-4 people, people were betting hard when they had nothing and trying to bluff out, people were chasing left right and center. Made for some big pots but man.

Do you find play totally different on weekends than during the week? I don't think I'm ever going to play on a weekend again after today.
