Isn't it amazing that we understand perfectly that the wind can blow one direction but it never occurs to us until a moment of revelation that it can blow the other direction as well. What you are proposing makes sense and could be very possible. If stress opens the floodgates the comparison could be to what happens when we flush a toilet! oops, there goes my dopamine!

But if that were the case couldn't we get rid of dyskinesia by just exposing ourselves to a small dose of stress?

A good piece of mental chewing gum all the same. I'll be checking in tomorrow to see what the over-nighters have to say.
