sleep supplement

I am a severe insomniac and recently started using CPAP. I have to use prescription meds to get to sleep. I have tried every natural supplement out there with no avail. None of it makes me sleepy, even taking multiples or combining. I am hoping to find something natural or other way to make my sleepy without scripts. Any recommendations?? I've tried everything. I am thinking about trying the Bono, the device you hold in your hand. I also dream excessively every night and all night. Open for suggestions for that too. Thanks
