amount of cigs i smoked, and i love it! I had a ciggy the other day and it tasted vile to me, so i guess that it has helped, and its easy to have a quick smoke without anyone knowing and also helps if you don't have a lighter :)
I have been a smoker for about 25 years. A week ago I bought an e-cig and it's been brilliant so far, I haven't craved a real one since then. I've already saved £15 - it will have paid for itself in less than a month.
