Did your doc prescribe a specific number of Lupon injections? My doc seemed to think I may be taking these semi-annual shots forever, He did allow a possible evaluation if my PSA becomes undetectable or if it goes the the other way and some escalated approach would be necessary. When we first started the lupron shots 18 months ago Zytiga wasn't even discussed. That didn't come up until 6-7 months ago. Hope all going well wiyh you.
