Pack and a half to two pack per day smoker for forty five years. Total vaper for two years now. When I initially tried to make the switch I tried using the Blu cigalikes. Major disappointment. I got some eGo's from a vape shop. Vast improvement, but still smoked two or three cigarettes a day for nine months. Then I underwent radiation therapy and smoked for three months. At the end of that I went total vape. After three weeks I couldn't stand the thought of another cigarette.
