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.

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.

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.

Menopause, perimenopause, childbirth and breast-feeding can all cause a woman's sex drive to shut down.

Your partner cannot read your mind, so talk to your partner about how you're feeling and what you need.

It's bizarre to me that you can have political commentators, sports commentators, weather commentators, but with medicine, people go, "You can't do that."

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