Have you asked about other options? Alternating acetaminophen & ibuprofen has been popular among the docs I've seen recently. Heck, around here many get a bottle of 800mg ibuprofen after a C-section, no opiods.
Ibuprofen might probably be ruled out, due to the stomach upset it can cause in larger doses, and they may not want the anti-inflammatory effect(?). But yeah, acetaminophen would work!
