I have been a smoker for 13 years. I have tried Chantix, It gave me nightmares and headache. So I was scared of quitting. But I found the laser treatment to be very good. I had 3 treatments in less than a week and have been smoke free from day one. I did feel some withdrawal symptoms but coaching made it easy to understand and handle them. Along with this treatment my decision to quit and the coaching which I have received to help the psychological aspect of quitting has made this treatment very effective and made quitting very easy.
