Yes, SI is a behavioral addiction. It's best to find a replacement that effectively addresses how you are feeling, whatever you might be stressed about, etc. Maybe if you get triggered you could tell yourself that's a sign that something is bothering you at some level that you might not be aware of, and try some active problem-solving to find what it could be and do something about it. Or, like Muse suggested, go someplace and do something fun, somewhere that you aren't likely to si.

Congratulations on not giving in.
