My mother has been on pain killers for the past 5 years, they started her at 500Mg of vicodin, to 1000 of vicodin, to Lortab, then to norcos, now to Oxy-morphone, a RX called "Opana ER". Ever since she got these, I would take them, I started out taking some vicodin here and there, to a full on addiction to the Opana ER, over time of course. My tolerance is so high, I take the same dosage she does daily, which is 4-5 20MG tablets a day. I need them just to feel normal. I have no pain.
