Oxycodone
"I would not be able to function on a daily basis without this medication.  I have been taking it for a few years now post lower back surgery.  I take 10/325 at least four times a day for breakthrough pain, because my Opana ER doesn't really kill my sciatica.  I don't know how I would do my job without taking pain management medicines.  I had been taking Endocet brand, and now the pharmacy has changed brands and I don't think the new brand works as well."
