Sleep is very important to help heal an injury. My husband recently suffered a spiral fracture of the humerus and he could NOT sleep without medication(darvocet). He took as little as possible as we are both anti-drug, but taking the drugs did help him. I would suggest researching the drugs you were prescribed. I think that there is a HUGE difference in taking pain/sleep meds for short period of time for a a traumatic injury vs. taking drugs long term for a chronic condition.
