Stopped smoking 60 a day when I was 32,put three and a half stone on in the first three months and lost two stone in the next three months. I was a swine to know for the first three months, then I got better. When I was 32 I had to climb a 90 foot staircase everyday, I stopped twice for a breather. When I was 60 I could still climb the staircase without stopping. With the record of cancer in my family I am sure i would be dead now.
It took me three years to stop wanting a smoke.
Stay with it mate it is worth it...
