I've not heard of him before. Quitting smoking is one of the hardest habits to break. Did you try this technique specifically for emotional eating or is this something new he has come out with?

A couple of decades ago I got a self hypnosis cassette tape for weight loss. You were supposed to play it while going to sleep and it went for about an hour. Supposedly your subconsciousness mind was more absorbable for stuff like that. While I did find it very relaxing, I couldn't get past the creepy feeling of someone programming my mind in my sleep! lol! I tried for a while and it didn't help. Too resistant I suppose.
