I see what you mean, I think. I read and post on SR every day. I almost never have any cravings, even when I'm around alcohol. I think the two things are very related. The stories here keep the consequences front in my mind even as the time since I've experienced them directly (thankfully!) grows.
I do play my own tape forward though when needed. Usually just in the form of the question, "Would I really even enjoy it at all, knowing what I know now?"
