Changing online poker sites

Why can i win games on partypoker but then on different sites i don't feel as comfortable and lose???? Anybody else had this problem?

Mostly it's probably all in your head. But depending on the games you're playing, if one site has a bigger player pool, it will have more fish and be softer than those with smaller player pools.

It may be something more subliminal. Try making the tables at all your sites look as much alike as possible.
