Pack a day smoker for 25+ years. Never able to quit. Got some ecigs after hearing it was a good way to quit. Not the cheapo disposables, good variable voltage Vision Twists. From the day they showed up in the mail till now over 2.5 months later I have not touched a real cig. Could not have been easier. Already cut nic level in half from 24mg to 12mg. Feel better, taste better, breath better.
