I used to smoke about 10 Castella Classic cigars per day, I inhaled, god knows what my lungs look like, but about 15 years ago I just decided I didn't want to smoke anymore, I was using nicotine chewing gum which gave me mouth ulcers, I tried the nicotine plastic cigarettes, it was costing me nearly as much for these items to 'kick the habit'.
A work colleague said I would be smoking again with twelve months, now I can pretty stubborn if I want too, so there was no way my 'mate' was going to win.
I was like a bear with a sore head to begin with, but days turned into weeks and weeks turned into months, etc etc etc.
So, I think your going to spend probably as much on 'make believe' fags as you would be spending in the real thing, and you will be back smoking within 12 months, now can you be as stubborn as me? prove me wrong and there's a tenner donation to a charity of your choice.
All the very best, you can do it, I did.
