It's tough man.
I started smoking when I was a Cadet in the Merchant Navy, not so many a day....GF then wife forbade me, so used to smoke secretly, took years and years of self-humiliation to go cold turkey and quit. Then started smoking weed, mixing a bit of tobacco, then was strangely hooked to smoking these mixed Js. Then went on to mixing weed with hookah and i was smoking A LOT of hookah with weed.
Then I quit everything, all kinds of smoke. Been one year and the desire, as far as I can see, is dead.
It was a bitter, dirty, ugly struggle but I always knew deep down that I would be here someday.
