yeah probably 5 weeks total.

once you get to the point of going a full day without one your probably ready (or almost) to just take the leap and quit.

on those days where you go all day with out, is it easy yet or are you still fighting it to not smoke?
if its pretty easy then you are ready if its still kind of hard give it another week or 2.


also one other thing that helped me
i got some shwag/mex/dirtweed whatever you want to call it (the cheap stuff)

i would take it and roll it up into pinners with thick cigarette papers like top's
then i would smoke the crappy thick paper joints when ever i wanted a cigarette like after eating : )
and if i hit it not like a joint but like i would hit a cigarette it kind of tricked my mind into thinking i had just smoked a cigarette
