I do. I made it a little more than 7 months recently. Slipped once so now I'm back to 9 days right now. Haven't done it again though. The last couple of times before that were approaching 6 months. Sometimes I just miss it, and look for excuses to do it.

In the past there were periods when I did it several times per week, interspersed with not thinking about it much for a few months. I used to stop cutting when I was really depressed. I was scared to try it then.
