You really don't need an increase of dosages most likely, just a better delivery system as Jomar has said above. Those that are looking for a high also want Immediate Release opiates, so asking for an Extended Release option should not raise a flag with your doc. It's not a bad idea to ideally have both, but if I could only have one I'd absolutely choose an ER option.

You might want to research Nucynta ER. It's one of the combo drugs that Jomar mentioned.
