How to negate confusion completely in Pokemon Black?

Is there a way to remove Confusion from the game? I just spent a literal ten minutes in a fight because every single ****ing time I switched out, the enemy ALREADY KNEW and decided to use Supersonic again. And instead of breaking out of confusion, they'd just slap themselves. Is there a way to just get rid of something so broken? I am not above hacking, at this point. I don't plan to connect to other people or participate in tournaments or the like. I just want to not be decimated by a feature that's been broken since it was introduced.
