I'm not a Twitter fan. I do it because I feel responsible to the two million people that follow me, but Twitter to me is just another thing I have do. And it's mostly a place for people to attack and abuse you. I don't really get much out of it, personally. I get hundreds of demands to answer the kind of medical questions that require three years of treatment to assess, yet people are furious when I don't solve their problems in 140 characters. It's really stunning.

We start with people who are motivated to get paid and be on TV, and we end up with people who have been transformed by the experience and go on to embrace sobriety. If they relapse, like most of my patients do, we continue to support and treat them. I'm thrilled that five out the eight [Celebrity Rehab cast members] showed up for after-care, and two more committed to coming back.

Every person is highly individualized so if a person is seriously concerned, then they first need to get a medical evaluation and make sure there's nothing biologically going on to prevent them from climaxing.

We don't let the past determine the future unless we allow it too.

No matter how difficult life becomes, there is always hope.

The very wealthy and the very famous have a much closer affinity with the indigent street person than with the rest of us. There's the narcissism, the addiction, even the outlandish dress. Often they don't put great value in relationships.

The experience we all share and the outcomes, which have been remarkable in a way I never could have predicted. Taking unmotivated people - maybe marginally motivated to get on TV and make money - and ending up with a group that values and is changed by the treatment process and wants to share it with other people.
