Re: just sharing own experiences...

Loon, this may or may not be helpful to you, but I've noticed a regular program on 3ABN TV which is a Stop-Smoking Clinic where a cancer surgeon (humorous older guy) stands on a stage to give his presentation, and has the attendees come up to share their experiences. Apparently, their success rate is pretty high.

They also have various programs on vegetarian meal prep, along with other healthy lifestyle programs (i.e., reversing diabetes), featuring MDs, therapists, et al.
