There isn't much work being done to discover more treatments, and most of the options out there are as good as it gets. The behaviour tracking bracelets (Pavlok, HabitAware, etc) can detect and alert you to your behaviour. Behavioural therapy can help detect triggers and help you develop coping mechanisms. The most recent research outcome was in 2012, which suggested movement decoupling (a type of therapy) as a potential treatment.
