I have the same problem, and I have found I am a lot less likely to do it if I keep them filed smooth and round. Carry a nail file with you for a week and do that when you get the impulse.
I think it always falls apart when the get dirt and oil underneath, and I try to 'clean' them. The answer to that is wearing gloves when working on dirty things, and being diligent with a nail brush afterwards.
