Perhaps, when you feel the urges to cut hit, get a pen and paper, and write about what you're feeling etc. This used to work as a delay tactic for me, and if you feel you can't write beforehand, write about it afterwards - just make a commitment to write either before or after. Obviously before being the preference.
It does get easier, and you can stop. I used to cut, and have been symptom free from that for 9/10 months now. It is so freeing...
