I smoked since I was 15 and am 62, so smoked for 47 years. Quit cold turkey about 3 years ago for about 1 yr and 2 months then started again. It was very hard to quit and had to fight the urge to smoke constantly. I smoked a pack a day. 11 days ago I started to vape and quit immediately, hardly any urge to smoke at all. About a week ago I took a couple of drags on an analog and had to put it out it tasted so bad. vaping is definitely working very well for me.
