You can educate people about politics, criminality, the law, but not about medicine? It's just silly.... I really don't want to hurt anybody, but to say the truth and to offer words that might be helpful in understanding what some of these conditions are. I can't see any reason not to do that. That's changing things for the better.

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

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."

I grew up in a Christian home, but was nearly 17 before I realized I had to make my own decision to place my trust in Christ. Salvation cannot be earned by doing good works or going to church, and can't be automatically passed on from Christian parents. Salvation is a free gift from God, who sent His Son Jesus Christ to die in our place.

I have a little theory about that, too. It's clearly envy. It's bringing people down to your size. It's a narcissistic impulse that didn't used to exist, but we've become increasingly narcissistic as a society, and envy is one of those outcomes.

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.
