I tried to quit many times and failed. The last effort was made the day my Dr. told me my circulation was bad and I might eventually lose my toes. He said that it starts with the toes and then maybe the leg. I went home, smoking my cig in the car, of course. But, funny thing, when I kicked off my shoes later and looked at my toes, I realized I liked them better than a smoke. I called the Dr. and asked for the patch, which he gladly gave, and never had another smoke. This was over 14 years ago.
My loved ones had been nagging me, my kids hated the smoke, and I just kept at it. Sometimes it takes a real eye opener. Maybe your husband had his eye opener with the neighbor. *fingers crossed*
