The only other thing i would like to try would by XYREM and growth hormone, both are very expensive and can help with sleep and general recovery.i have heard the odd person say that growth hormone has fixed their sleep.
I have tried growth hormone. I did badly on it. Made me worse. The hormonal experts say that growth hormone is the last hormone you should correct/supplement when all the others have been corrected first. I don't know if that is true, but certainly fits in with my case.
As for Xyrem, I wouldn't touch it with a bargepole. It can depress the CNS/respiratory drive, so potentially very risky. I have actually tried a drug for sleep which is chemically similar to xyrem, and it did depress my respiratory drive, so I am extra cautious about xyrem.
In answer to the question, if money were no object I would do some kind of environmental cure. Move to a pristine stress-free environment where I have my own personal chef cook salutogenic food for me. I'd also get daily massages, and other daily therapy. I'd have a personal assistant to manage everything so I could concentrate on being a patient, and not have to play doctor/ researcher / carer / organizer for myself as I currently do.
Somewhere near the beach/sea would be nice. And somewhere with some sun ...
