I lose interest quickly when using self-help books, I have to work hard to stay motivated. That's why I love the tapes. When you first start with the series it's an easy schedule to keep. Each CD is an hour-long "session"; I usually listened to one "session" a week and for the rest of the week practiced the new techniques that were taught. This is the equivalent of a therapy session, only it's not interactive; but Dr. Richards really understands what social anxiety is all about, unlike most therapists I've been to.
It is true that CBT will not work as quickly as medication. But I personally don't like to think of medication as a solution, I look at it as a crutch that I will eventually no longer have to use.
