Hi someone who is not me has a 30mg Avinza ER (24hr Morphine ER) and a 5mg Oxymorphone ER (Opana)... This person who is definitely not me would like to know if they are safe to mix with each other if the Avinza was taken in the morning and the oxymorphone later that night... Anyone have experience with this? This person I know is very cautious and doesn't want to slow his heart rate down to a crawl and die in his sleep.
