I thought I would never be able to give up smoking tobacco, even though I have had lung cancer. However, I gave up cigarettes on 30th June 2015, and haven't had one since then. I am convinced that e-cigarettes have dealt with any craving that I would have suffered without them. Not bad for someone who had smoked for 63 years. The financial saving is immense as I smoked at least 20 cigarettes a day prior to finding e-cigs. Brilliant !!!!
Needless to say that I have recommended e-cigarettes (via Vype) to many people. Cheers.
