From a former 30 year, 1.5 PAD smoker - much congrats. I know just what you mean: I gave up even trying to count the times - and failures - to quit before I came onto e-cigs. Haven't touched one since July 31st of last year, can't ever see going back. If you got in 16 weeks with 0 cigarettes you must be set too.
Family is good but you got family here too. If you ever have any questions ask away. Best wishes for continued success!
