    Although I'm not a Doctor, I strongly feel that using opiates such as Morphine Hydrochloride or Fentanyl would do a better job of controlling the pain, probably be not much more addictive, and have less debilitating side effects. You should be seeing a pro in a pain clinic to discuss changing your meds.

    Until above mentioned pro approves in writing I would not recommend either diving, flying, operating a car, riding a bicycle, or walking outdoors alone. You're an accident waiting for a place to happen.

    Re: pain killers

    Gabapentin is usually pretty well tolerated. I dove recreationally while taking it. But the herniated disk also never got better and I ended up in surgery anyway (possibly because I continued diving but who knows).

    I don't know about the second one, but it sounds like a fairly strong analgesic. Regardless of the depth and ppO2 possible interactions (which probably aren't known anyway), I am more concerned about the underlying condition you are taking these for and whether you should be carrying heavy cylinders, CCRs, weight belts etc.

    Are you actually cleared to dive with all the activity that goes with it by the prescribing physician?

    Be careful asking a question like this on a forum... loads of armchair physicians, EMTs, and divers. Best advice has been given: CALL DAN! 1-800-446-2671
