personally, I switched to methadone and like it a lot better, though it can be tricky to find an effective "breakthrough" medication that will work alongside it at the right methadone dosage for your primary pain......fentanyl is generally the best choice for that. I take hydromorphone (dilaudid), and I have some doubts as to how well it really works through the methadone's blocking effect.
