HOW DO YOU PREVENT TILTING

[josh3336]

I tilt so badly. I'll win hours upon hours then take a bad beat and lose it all in the following hands. I can't help it I just get so angry. I yell, I scream, I punch things then I proceed to lose my winnings. I watch it all slip away before my eyes. I tilt midhand when I know they just caught something and call out of spite I can't help it. Like I just flopped a straight and I put this guy on a set then the board was running 3's on the turn and river and I knew he just hit a set and rivered a boat but I check called him anyway cause I was pissed off. I can't help it.... Any suggestions?
