I didn't smoke much ~ 20 a week or sometimes 20 a fortnight. Used to smoke more but dropped it right down about 15 years ago.
Reached a point where I wasn't comfortable at all with the risks from social smoking and a mate got me onto vaping.
3 months on, and I haven't touched a smoke, nor do I want to. Survived a stag do for 3 days in Amsterdam with no cigs.
Smell better, things taste better, exercise is easier, less expensive, improving health.
Next up is dropping the nicotine level in e liquid so that I'm on zero nic by this time next year, then kick the vape altogether.
