Sounds like a real mess with the meds - check out the information on ces & sound & light machines which you can find at alphastim.Com & also dynamind.Com (alphastim got them first so has more information but they cost more - alot more than dynamind & my dr says they're the same thing).
These may not help you but i'd think they'd be worth checking as they wouldn't interfere with anything - the ces machine has helped my migraines, sleep (or previous lousy sleep!!), depression/suicidal & anxiety in only a few weeks.
My dr does prefer to look for non-invasive solutions & is opposed to pharmaceutical companies making $$$$ off patients when there are alternatives which work better & last longer without side effects!!
