I hate his promotion of Celebrity Rehab, and I recall allegations of how he just actually specializes in Internal Medicine and doesn't have the qualifications needed to do the work that he does. I think when he was still back in the Loveline days he was paid to promote Wellbutrin (late 90's when it first came out). Was involved in a criminal investigation because of it. Now there have been 5 deaths from members of Celebrity Rehab. It's a sideshow that shouldn't exist. Some of these people (like Mindy McCready and Kenicke) needed a hospital, not a reality show resort.
