pain meds
I and few other guys around here know EXACTLY where you're coming from. The pain from three herniated discs in my lower back was so bad that was on hydrocodone (vicodin) 24 hours a day. Of course my body built up tolerance so I kept taking more and more, and physical dependency and some component of psychological addiction all followed as well.... I had to struggle under the care of a pain management specialist to find the right treatment plan. We tried a few different things before we figured out what worked. With each try, he gave me a plan to taper or wean myself off the narcotics so the withdrawals were much easier compared to going cold turkey. What worked in the end for ME was MS Contin which is an extended release oral morphine - much different in terms of intensity from IV morphine which was a good thing for me. All it did was take care of the pain and that was it. No euphoria, which at first is a bummer, but that is what makes it so much less addictive. Eventually as the weight fell off so did the pain, and now I don't have to take anything at all for pain - so when people asked me what did I do to cure my back pain I say I had surgery, then I explain it wasn't a spinal fusion that cured me, it was RNY - I love my RNY!
Jim, Fentenyl ranks up there with morphine in terms of addictive potential. I hope you are seeing a pain specialist. Norcotics and synthetic narcotics aren't great choices for long-term pain relief due to rapid habituation (and consequent dependence). Have you tried a "medication holiday" - a period off all pain meds that will allow you to get a baseline read on your pain (especially with your weight loss)? Working with a pain specialist you might find better alternatives to narcotic pain control. When I have taken morphine or morphine synthetics I find that they peak in terms of effective pain relief in about five days. After that codiene, tylenol or ibuprofin work about as well (of course, check with your bariatrician, too.
I have worked with a number of people addicted to fentenyl as an addictions specialist. You might be in a pattern of addiction/cross-addiction and it is possible you'll feel a whole lot better if you explore some alternatives.
Good luck,
