They say after 2 years the chance for relapse drops tremendously so keep it up brother we are here for you! I hit my 2 years sober last month but I was on meth or high doses of Adderall for about 4 years so I feel you on that "never thought I would stop" thing. Before that I was doing anything and everything that wasn't a downer, it was the only way I knew how to deal with shit. Glad to hear you are doing good and feeling better!
You need this song in your life, hit me good when I was dealing with urges or whatever.
