Wow. Have you done muscle-testing/kinesiology to receive more insight?
I also was wondering if there was an underlying reason why you needed more sleep, and if THAT was the root of the problem, actually. A lot of us have been sleep deprived, but do not have such a lifelong reaction to it.
I wonder what the nervous system correlation is?
It sounds like you are doing everything right. It'll happen over time, the way it should. Good for you!
