For anyone thinking about quitting... I'm just 3 months in, having quit a number of times, sometimes for long periods, only to end up back on the weed again, here is my current update.
The first week is easy, it gets progressively harder as time goes on to not say... "just one won't hurt". It will, one will become two, two will become three, three will become I may as well just finish this packet.
So, "not once, not ever" is the only way forward - in my humble opinion of course.
A few weeks on, you start to hack up all sorts of crap. 3 months in and I'm still coughing up phlegm with flecks of crap in it. Its much less now, but still there. I can breath SOOOOOO much better, the gym is not easier, it's possible! It really is that much different. Previously I would come from the gym, looking like death, sneek off as fast as I could so I could spark up and not feel like a freak for working out and then smoking.
I smell smokers now..... they stink. Simples. I NEVER want to smell like that again.
I get the odd urge to smoke, not often, but once in a while.... then I smell a smoker and that's enough to make me laugh at the thought, rather than take it seriously.
I'm severely anemic for some reason the Dr's haven't got an answer to, but they are looking into it. And yes, I was hacking up blood at one point - thankfully that seems to have passed.
6 months is my next target........
