I take Opana ER, 80 mg twice a day. I've been on pain meds for 20 years. I don't abuse them but my body is physically dependent on them. My Dr wants to taper me because she says I'm too high on the medication. I came to her at this dose. She told me today shes lowering one of my doses in half. Take 80 mg in the am and take 40 mg in the evening. That's way too high of a taper from what I understand. I heard you taper in small doses over time. What do you thing about this? Too much of a taper?
