Severely Oily Skin + Blackheads

I've had acne since I was about 9, I'm 22 now. It's gotten better as I'm growing older, but I still can't get rid of the blackheads on my face. They're not really black, a flesh color, but I know they're there, and it seems almost as if every pore on my face has one in it, no matter how many I squeeze out, no matter how many times I wash my face, they come back the next day. I've gone on a sugarless diet, and that cleared up all of my white acne, for the most part. I have such oily skin, that I don't even have to moisturize after using any acne products, and for the most part, I've tried a majority of them. Proactive, Nuetrogena*sp*, etc etc...Anyone have advice for severely Oily skin, aside from a diet change which I've done already?
