There is a sleep thread here with lots of info and suggestions:

Are you having trouble falling asleep, or staying asleep, or both?
For trouble falling asleep, some natural things to try are melatonin or Hyland's Calms homeopathic tablets.
If you have trouble staying asleep, you might need to work more on resetting your circadian rhythm.
There is also a good thread on nutrition here:

Have you considered seeing a physiatrist (one who specializes in Physical Medicine and Rehabilitation)? Many of us have found this type of doctor more helpful than neurologists, etc.
Welcome and good luck!
