I was told that my body would take care of it, I have a bit of tightness every now and then, but never when I ride, only resting.. Haven't felt the need to pop some nitro yet, but the doc said to try it out..
The only thing that bugs me is the beta blocker and keeping my heart rate down, sometimes I just can't get the HR up to a decent amount.. I'm on the lowest dose though and my resting rate is around 50..
Good luck, hope everything works out for the best, keep us updated and ride hard.
