Effective Medications

I was placed on Lamictal for bipolar earlier this year--and I found to my great surprise that it was tremendously effective in removing the compulsion to skin-pick, in reducing the desire to overeat, and even in helping me to file papers, which I normally have a lot of trouble doing. Has anyone else found a medication or medications that helps them with skin-picking? Or, better yet, with multiple "co-morbid" issues?
