Thanks, Kaitlin.  The workouts that got me were a 5:00 amrap KBS/burpee and 4 rounds of run/wall ball (in 7:37).  More intense than I’m used to, and my training had been inconsistent going into the start of the CF program.   Symptoms were mostly the same for the rest of the day of workout: frequent feeling like I needed to clear my throat and infrequent cough.  The next day those were gone, but could still feel a remnant of it at the end of a big inhale.
