I think you are in a middle area, where shadows and the occasional hits are expected. This is not a exact science... meaning to say that your continued visits by the beast, being as diminished as they are, are sometimes the best that can be expected. There is no cure. You will find the substance and frequency that will give you maximum relief... and that may not be total relief. Be thankful of what you have found, and keep experimenting to find your own maximum relief level.
Good to see you are doing better.
