5 years sober

I've been clean going on 5 years, but still get cravings for meth. I've filled all my free time with mostly work. Though is still have hobbies like metal detecting, gaming, and "prepping". My wife is a huge contributor to my sobriety, but she is gone for a week seeing family which has me unsupervised. I know I sound like a kid saying that, but I was introduced to drugs at 8yo by my parents, and the only other time I've been some what sober was prison. Since I've been out, I haven't even touched a cigarette. She has kept me in line and away from old habbits. Now that's she is gone for an extended period of I can't fight the urge to use, bc I know she will never know. Any pointers?
