Sorry if this sounds combative; I'm really just trying to understand.

What makes you decide to retrain, if it's working so well?  Do you
just do it prophylactically, like brushing your teeth?  If so, then
you probably don't see it improving things much (like brushing your
teeth).  In that case, what makes it rewarding?
