Hi ladies....I am taking Endocet 7.5/500 every 3.5-4.0 hrs. If I don't stay on top of the dosage I am on excrutiating pain. My surgery was 12/3. How long can I expect to have to continue taking the pain meds. Would I be okay to just switch to Tylenol for pain? Anyone been on the pain meds longer than a week? Thanks!!!
