I had the best experience with Dr. Grey. I went to him to stop smoking and I walked out of his office and never smoked again. And it wasn't even hard. It will be two years this May. It is like I never smoked. I have no desire to smoke. And I smoked a lot and for a long time. In fact my husband smokes and it doesn't even bother me. I am so grateful to Dr. Grey. He fixed me in just one visit. He really is amazing.
