I would imagine that this would have no impact on symptoms since copaxone wasn't developed to impact symptoms at all, only slow the progression of the disease. So changing the frequency of injections "now and then" probably wouldn't be noticeable unless you seemed to develop new disease activity or something like that. But since Copaxone isn't supposed to affect existing symptoms, I don't think that should be your measure of how your chosen and variable dosing schedule is affecting you.
