i would first say get off the diazepam and amitriptaline. it may be that you need to increase your fentanyl patch. over time your body will develop a tolerance and you need to adjust your dose accordingly. also, ask for something like roxicodone (oxycodone without the tylenol) for BT pain. one more thing is try cymbalta, which is an antidepressant that can help with pain and may help with some of your other issues. i would advise being on an antidepressant anyways, but try to find one that doesn't make you sleepy. you may find you do better with the lyrica if you are on an antidepressant. you could give it a go again. try it for two weeks after you are on an antidepressant and see how it goes. it may help and not affect you the same way.
