Here is what I do when running bad online....

Switch games from limit to NL or sit and go tourneys. I know you are probably running bad from unpleasent cards but that can cause someone to misplay their good cards as well.

I know many people oppose switching games from limit to PL, NL, SNG etc but remember the point of poker is to win chips and who says that you need to stick to one variation of poker anyways?

I always come back to my main game (limit he) better and fresher after doing this
