I have now been a non-smoker for 11 months after almost 45 years (and any number of attempts with gum and wonder drugs) with no intention of ever smoking again. I have no problem being around smokers, and I no longer need my asthma puffer! The process is really gentle and incredibly relaxing. Dealing with Debbie is an absolute delight. And how can you go wrong with a lifetime guarantee? Love your work Debbie!
