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.

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."

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.

Medications can lower a woman's sex drive and interfere with a woman's ability to climax. These medications include antidepressants, birth control pills and hormone medications. I only know of three antidepressants that do not interfere with a woman's sexual function.

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.

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