I suppose I never reach normal but am content (thrilled!) if I have no urgency. Seems like you still have some symptoms, maybe try the fiber suggestions at this point? Spinach, metamucil catch my attention. I think the spinach helped me, I didn't try the metamucil because the wafers have gluten. When I hear about episodes like you describe, I have to wonder if it is triggered by food you are sensitive to, or fiber issues.
The prednisone is a bit trial and error. If you go off and your symptoms increase, then you might be one who still needs a small dose, 5 mg or less, for a while.
