Congratulations on a week! That is really the hardest part, now don't get complacent, That is what fucked me over so many times. At the end of the day, a week sober is nothing, so don't reward yourself with a hit yet because of how well you've done (that is how my brain worked at least). You know what got me off the pot? Having to pass a drug test to land a 100 K a year job, that I only work 2 weeks out of the month to do. Passing that test is such a tangible goal, when shit gets rough just keep that in your head, and keep coming to this thread. It was a huge help for me anyway, to know there were other people struggling, and that I wasn't alone in it.
I passed my test, it must have been six months now, and I have smoked a few times since then, and you know what, given enough time off, you might just find that getting stoned isn't all that you remember it to be (especially after being a chronic), you will be to fucked up to function after a month off, I couldn't go outside for a bag of chips even, or socialize the same way with friends, and most of all, I couldn't ski or ride my bike stoned like I used to, and that was a real turn off for me. Good luck!
