Hang in the oliver, it gets better.

No matter what, it gets better

Couple of things to avoid, dont hang about with your mates when they stop for a smoke, particularly when having a beer or two. Tough but its easing the pain by keeping away for a while.
If you crack, then start again directly.
Couple of things you will do is look for the smokes, like patting your pocket. That will fade.

You will ask those around you all about strange fresh smells, that's cos the system isn't clogged up.

Don't listen to theDoctor, he sounds like he has given them away as well, and slamming all over forums
