I definitely feel for you! I'm on methadone so I geuss I'm not technically 'clean' but, I haven't used my drug of choice for quite some time now. But even after all these years I still dream of using! Its so strange because in the dreams I don't even think about the consequences, like I would do now IRL. Theres no hesitation at all....I just go and try to find somewhere to use, and most of the time I wake up. But then there are the times where I do use and actually feel it....frustrating!
Fortunately, these dreams are coming less frequently.

Hang in there! The longer you give your mind and body away from that lifestyle, the easier it gets.
