I am transitioning from 30 Oxy ER to a Opana 20 ER.
A month went by, i am still in a process of transitioning and despite Opana 10mg x 4 a day and Opana 20 ER x every 8 hrs - i suffer so much from withdrawals.
Forgive me please, but i also suffer with bowel issues. All opioids cause constipations, but seems Opana is much worse then others.
Am i imagining it or someone else can share similar experience?

Thank you in advance
