The sudoku made me do it...

The University Register is our school's weekly newspaper. I has a comic and puzzle page and on it is a weekly sudoku. This week's sudoku has a difficulty level of masochistic. I don't know where that falls in the easy/medium/hard rating system. But I can atest to it's difficulty. I have spent waaay too long on it. Like, at least two hours on it tonight. Had to start over twice and each time worked myself into a impossible solution. It's horrible. I've been relearning all my old techniques in how to solve this blasted puzzle. But yeah, it's hard.
I was going to post it, so you all could give it a shot, but I've had too many things ruined by people using online solvers. Sooo, maybe after I finish it.
