I have the same problem. I went a while without doing it, just by forcing myself to stop. Oh my goodness it was so difficult.<br />
Of course I gave in, but now I have some control over it :D
I have a hard time with it, too. I can't completely stop, but I moderate myself. When I feel the need to pull out my hair, I'll only do a FEW strands :(<br />
At least it's thick.
