Interesting timing:

I have gone through the piecing forums reading what people are doing, how well they're doing, current state of mind, how "bad" their situation was to begin with. I would be VERY interested in what sort of success numbers come out of that, and what type of situations were successfully resolved, the dynamics of the individuals involved, and so on.

It struck me the other day when I saw someone post - they were back after DBing 4 years before. I lost the post, but I really wanted to see what caused it - WAS regression? Simple failure to follow through? Just didn't work?
