You know my DBT group therapists and my T don't recommend any of those. They think it reinforces the pattern instead of actually changing patterns.

Instead they encourage urge surfing, distraction, and utilization of the distress tolerance skills. I dealt with SI and just by practicing the standard skills over and over again my urges just... faded. I mean, the thoughts come into my head but they don't stick and I don't really feel like indulging. Like, I'd rather go do something else (that is, a skill). It's hard to explain. :-/
