I had a bad arthritic hip for years. I was using up to 14 oxycodin pills a day so I could work. I received my hip replacement and the pain is gone. It seemd that I cannot funtion well through day without taking the oxycodin. My doctor prescribred me Ambiet (10mg) and I take two and can not sleep. I was never told how musc to cut down on the oxycodin so it has been all guess work. Sometimes I take one, sometimes,two and sometimes three. In any case, I am not sleeping. Do you have any suggestions.
