I have had periods in my life where nothing worked. During these times my doc prescribed Xyrem. It is very strong and most doctors won't prescribe and few are familiar with it. Only one pharmacy produces it as it is the legal form of GHB. It is a liquid and tastes bad so you have to mix with something. After a few months you may want to wean off and see if new sleep pattern has emerged and you can do it with trazadone or a normal sleep aid. It works for me everything else fails.
