I don't know what you use now or what you have used in the past so if I mention something you've already tried, forgive me.
I found Neurontin to be the best med for sleep ever. It produces a very natural falling asleep and I slept all night. I woke up with absolutely no hangover effect, just very rested and refreshed. It's actually an anti-seizure med but it is used for post-op pain, neuropathies, and anxiety. Here's a link to some info on that:

Good luck, and good for you for researching prior to your doctor's visit!
