After tapering for about 3 months, I am on:
10 mg Opana ER and 5 mg.Opana IR in the early am;
5 mg OpanaER and a 5mg OpanaIR at noon;
5 mg Opana IR at 3 pm, and:
5 mg Opana ER and a 5 mg Opana IR around 6 pm.

Can you suggest a plan to taper down from these?

I really appreciate it. I am having to take more in the morning because I am soooo anxious. I guess the Opana is out of my system after sleeping.
