Well done mate, it might only be 14 days but that is 14 days i bet you never imagined you would do when you were addicted to nicotine.
I've done 7 weeks now and fully consider myself to be a non smoker. Don't get me wrong, I still get the odd, totally unexpected 'I could murder a ciggy' craving but as time goes on you just learn to shrug it off.
I have recommended Allen Carr's 'Easy way to stop smoking' book to everyone I know who wants to quit and if you find it difficult at any time give it a read.
Congrats on doin 14 days!
