Hi ladies: i'm so happy that i saw my OS today. The doc at the rehab had changed all my meds and was the one who thought i could be on Percocet at night and Tylenol all day....I'M TELLING YOU, I WAS CRAWLING UP THE WALLS IN PAIN. Now that i've got my revised directions and have been on 1 Percocet every 3 hours, my pain feels like its finally under control. I'll leave that possible 2nd pill for an evening where my pain gets too intolerable.
