Ive been quiting smoking since I was 28, I started wen I was 12.
Its been rough and Ive tried almost everything to quit. Patches 3 times, hipnotisim, cold turkey a few times, havent tried accupucher, not gonna either.
I wanted to quit at that time becos I started lifting at that age and I wanted to quit for the same reason as yourself.
I found my workouts to be more fruit full immediatly, especially with in the extra nervious energy I had in the first few days.
After a while blood preasure and energy levels return to a normal healthy level. I found I could do more and lift heavier and do far more reps.
But as you may already know its all about breaking habits, I just learnt that wen I craved a smoke to delay having one and letting the moment or moments pass. thus breaking the cycle of habit. (even if you have a smoke after the feeling passes, your still breaking habit.
Everyday was hard for the first 3-4 weeks but each day was a little less tromatic then the last.
For me now its just a matter of staying away from wanting to smoke if I have a drink.
So I simply dont drink or try not too.
Good on ya my man and I hope you quit for good it will be the best thing you ever do.
