I quit two years ago using a variety of nrt patches, gum and the inhalator. I used as much as I needed when I needed it. When socailizing I used the inhalator, I had a patch on all the time and I used gum when I felt the need. Gradually I cut down on it all but not before I was ready. I have quit twice this way. It is staying quit I have a problem with. Two years now though
