I smoked for 20 years. I stopped a couple times but always returned. Nicorette and patches I found to be useless. March 2012 I had a haemorrhagic stroke and was hospitalized. At this point I switched immediately and completely to electronic cigarettes. I started w pen-style devices and then graduated to a ProVari and an eGo-C Twist w a Kangertech Protank. I havent smoked tobacco since. There is no temptation. Vaporizers are absolutely positively the best and only way to successfully quit smoking.
