The cravings definitely aren't as intense or persistent once you make it past the acute withdrawal. There are things that you can do to diminish the cravings even more, but some of it may require a lifestyle change and isn't always practical. For instance, avoiding stress for the first few months might help reduce the risk of relapse, but isn't always possible.
There are more practical steps that can be taken. A lot of people report success with cognitive behavioral therapy, or just therapy, counseling and groups in general. Addressing some emotional issues can also help to reduce the urge to use.
But I don't think it ever really goes away completely. Hopefully I can get to a point where I'm not thinking about it that much. I can't say that I'm there yet, but I have definitely made a lot of progress.
Do they do random drug testing at your work?
