hey Nick hope your sober by now! Join a NA or some sort of support group, it can help a lot. I joined the military and that was my way of dealing with my fear of relapse, cant use and abuse in the military, not saying thats the end all be all but, it helped for me. Without it I probably would of relapsed multiple times, I didn't have anyone to fall back on, I didn't see any therapist, in fact, I didn't even tell anyone about my addiction until about one year into the military and I was getting some pretty strong erges to use again but, I knew if I did then popped for a drug test that would be my life down the line forever tarnished with an other than honorable discharge from the military. This pushed me to stay sober and I actually did relapse but it was a hit and quit, instant regret right after I was honorably discharged.
I don't want to talk about my story we each have our own but my point is find something to keep you sober, a friend to tell them to monitor you and punch you in the face if you ever used again, a group, a good job that drug tests or w/e. Something, it helps a lot and you will only benefit from it. Not saying you will get a craving to use again but it happens, just stay strong.
