Heres what I did , and so far its worked for me. I was a pack a day plus smoker for over 40 yrs. I knew I had to quit, so every time i had a craving Id hit my e-cig. I did that for 3 days. I still craved a real cig so i decided to light one up took 1 drag it tasted like crap. That was 13 days ago and I havnt touched a analog since...... For the first 3 days your body does alot of wierd things, yove got to remeber your addicted to alot of the toxins in a analog also. Just takes time for the old body to readjust. Stick with it and youll be fine......
