Welcome to SR!!
I, too, am a recovering crack addict. I started off, in early recovery, when the cravings would come I'd tell myself "not an option...next" and "next" mean to distract myself. I also vividly remembered my relapse, and it was ugly...couldn't GET high enough to drown out the feelings of shame, hatred for myself, etc.
In time, I would find myself distracting from a thought I didn't even realize I'd had about crack. I have a little over 4 years, and I've been through a LOT but the friends I've made here have gotten me through everything. When I was robbed at work, the 2nd time, and pistol whipped, while I was sitting in the ER, getting scanned and stapled up, all I could think was "let me get home to SR". SR has been that vital to my recovery.
Hugs and prayers,
Amy
