Tramadol in particular is known to help with depression, and is sometimes prescribed off-label for it. Some other opioids are, to use my PM's term, more "activating" -- that is, give people more energy. I have found that to be the case with hydrocodone, and perhaps with low doses of oxycodone (higher ones make me more loopy).
Although Tramadol is not a strong opioid, maybe consider adding it to your regimen for its dual function?
Cymbalta is also worth discussing with your PM as it is an anti-depressant which also has benefits for pain.
