I tried Moraphine years ago and it just made me sick. Same with the patches you can wear for days, after 6 hours I would be vomiting. I believe they were moraphine patches. Others could tell you more about it.

I like the Methadone. Don't know if you have tried it but it seems to have the least side effects.

I believe with any med sometimes the Drs. start patients out on too high of a dosage and their body can't get use to it.
