Shayatanica, that's pretty much where I'm at now. I don't even notice I do it. I try really hard not to for my aunt (my parents have given up) but every now I slip up, or it just hurts too much.

DrSkipper, I'd be a hypocrite if I told you to stop, since I'm pretty much in the same place and I can't stop, but if you haven't started to hurt yet, it'll get there, and it's not fun, and try and stop before it hurts.
