I didn't smoke because i was addicted, I smoked because i enjoyed it (obviously i was addicted to. but that wasn't the reason i carried on, my partner tried to force me to quit and i lasted 7 weeks before going back to it, because i enjoyed it!)
so yeah I really really really enjoyed a smoke, but my smoking had never affected my fitness until recently, I used to rock climbing, and mountain walking with my in law's without losing a breath, i'd get to the top first and i'd be smoking all the way.
Fast forward 2/3 years and now i can't go round a golf course without losing a breath, that EXACT moment was the moment i switched to ecig's because i wanted to carry on "smoking" because i enjoy it but i don't want my fitness to be affected.
I have a pouch of tobacco on my desk that is 3/4 full but i never reach for it, only my PV because it's just as enjoyable but the difference is my lungs are healing and i'm getting my fitness back.
Trust me, stick to the vape and you'll soon realise what an absolute god send it is.
