Narrative:
Having accepted a descent clearance to FL190 and approaching FL190, we received additional clrncs from mia in addition to a speed reduction. Having passed through FL190, immediately notified ZMA and received a clearance to descend to FL180. Descent was stopped at FL180 with remainder of flight being uneventful.
