Melatonin might help.....as might a few other "sleep aid" supplements/OTC medications though the most common, Benadryl, Dramamine and Doxylamine (the active ingredient in most OTC stuff marketed as "sleep aids"), I'm not a huge fan of personally.
It's possible that prescription medications might be more effective, but again, many of the most commonly prescribed for sleep are, in my personal non-doctorial opinion, not such great things -- for example, Ambien which has some horrid side effects (sleep walking, amnesia, weird behavior, the non-time-released version will help you fall asleep but not stay asleep more than a few hours for most people so it doesn't address your 5AM wakeup problem, etc) and isn't really a long-term solution.
Then again, taking melatonin long term isn't the best idea either as it will suppress at least some of your own natural melatonin production (which may be low to begin with, given your insomnia).
Personally I have always found the antihistamine/anti-nausea/anti-vomiting medication Promethazine to be tremendously helpful for falling asleep, having restful uninterrupted sleep, and sleeping for a long duration -- in fact it often caused me to sleep much longer than I would even back before I had insomnia.
However, now that I am having my existing insomnia made significantly worse by the benzodiazepine withdrawals as I undergo an aggressively paced (much faster than recommended, though with many aids to ease the process--that said, few things really make much of a dent in benzo WD) valium taper....promethazine is a big help but doesn't make as big of a dent as it did before because your GABA system, which benzodiazepines activate by making your GABA receptors "more receptive," is very important to proper restful sleep. Since my GABA system (and the others it interacts with such as NMDA and Glutamate) is so far out of wack from benzo WD, virtually nothing can punch through the overstimulation and other sleep-disrupting symptoms it creates. Making several small dents is about the best I've been able to do.
Purely pain related insomnia--and I'm not saying that's all you're looking at, as someone with your condition and taking the medications you've listed could have any number of other things contributing to the problem as well--is a tough nut to crack. Controlling the pain is pretty much the only single long-term solution that I know of; compensating for it in other ways is a very complex process and often involves rotating different things because you will eventually become tolerant to most of them and they will stop working, or at least you'll have to end up taking more than recommended....which is sometimes OK, sometimes not so much. As I said: it's complex.
You mentioned your doctor won't prescribe "sleeping tablets." Maybe, particularly if you don't specifically say that it's for sleep, asking for promethazine tablets (I'm not suggesting you lie, but if you have any problems with nausea etc, you could get them for that reason and then use them for dual purposes) might be something your doctor would be more receptive to. You could also inquire what things you haven't tried yet that he/she suggests for your insomnia.
Also, "adjusting to it" may be part of your problem, even though it's a coping mechanism I recognize all too well from my own reactions to feeling like I couldn't sleep even if I wanted to at a given (usually obscene) hour of the night.
Oftentimes, having a light on bright enough that you can read a book is enough to suppress melatonin production and other sleep-inducing processes in your brain. Total darkness is essential to falling and staying asleep. If you must have ANY light exposure after your ideal bedtime hour, it should be toward the red end of the spectrum and contain as little blue light as possible, as it is the blue end of the spectrum that activates the "wake-up/stay-awake" systems in your brain.
Doing anything that makes you think, or keeps you stimulated in any way, will also keep you up even if you feel like you couldn't sleep anyway. It may not seem like those things are part of the cause, but they are definitely contributors -- I know this from my own personal experience as I often find myself watching videos or doing things on the computer, using my iPhone, listening to music, etc etc to keep my mind off how terrible I feel from the severe sleep deprivation that goes on for weeks on end.....and recently since I *forced* myself to stop doing all that and just try to go to sleep as close to my ideal bedtime hour as I possibly can, I am actually much more successful in doing so.
Our cases may be a little different since as I said I am currently dealing with some big complicating factors on top of my very severe (and currently untreated, as a few months ago I went off pain meds since I am between doctors) pain...but the fundamentals of the problem are generally much the same.
I hope all this helps at least a little. Following all my suggestions would produce the best results I believe, but if you can follow at least a few of them, it should make a difference. Good luck and rest well!
