I've been sober for quite awhile now and one thing that i've noticed is that when i do get the urge to get loaded (whatever the drink or drug may be), it goes away. But sometimes it lasts weeks at a time. Those are the scary times.
When I was early on in recovery, I attended both NA and AA although drinking was definitely always my bigger problem. But reading some of the stories in the back of the NA basic text triggered the hell out of me to use drugs that I had never even considered using before. Someone very wise who helped me greatly in my recovery used to always say, Anything that you haven't done, tack a 'yet' onto the end of it, and that's what's waiting for you out there in active drinking/using.
Best of luck.
