That is wonderful to read UMASS!!! I have had pred end a cycle for me. Of course it was not my standard Sept, lay low time either!!! My guess is that if you have been off the pred for 3-4 days and no hits, you are likely good to go.
Suggestion. I keep a taper pack on hand so if needed due to travel or weather and I am likely to get a random cycle started, I take it. Usually happens about twice a year. And it is just the standard taper pack.
