Rich,
Stick to it mate.
The first few days were awful for me - made me really unwell
....... BUT, I now consider my self a non-smoker, not an ex-smoker. Really pleased I've given up.....
My stats are nothing compared to Stu, but:
Not smoked for: Two weeks, six days, 16 hours, 25 minutes and 15 seconds.
268 cigarettes not smoked, saving £66.95
Life saved: 22 hours, 20 mins
