Smoked for 18 years, quit for 5, then started smoking on/off for the last 4 years (time goes fast!). Stopped again at New Year, will see how it goes.
Most of the time I hate it and know how much damage it’s doing, especially at the top of a nasty climb. In contrast I ran my best half marathon 3 years after quitting, I can remember being amazed at how much I could breathe and how strong I felt.
Unfortunately I also REALLY enjoy smoking. Just thinking about sitting in the afternoon sunshine with a pint or a G&T and a lovely smelly cigarette makes me want to go and stand in the rain and look sad. MMMMmmmmmmmmmmm.
