Hi Capn, welcome.
Coupla things...
Do you have a specific headache diagnosis?
Is your current neurologist board-certified in headache medicine? IME of many years with chronic headaches, I've found that while most neurologists claim/think they know how to treat headaches, they really don't—not the difficult ones like us, anyway. I didn't start getting results until I found a headache/migraine specialist—one whose practice is limited solely to headaches migraine. Since then my headaches have gone from chronic (>15/month) to 1-2/week.
Are you keeping a
headache diary/log/journal? If not, it might be a good idea to start one. It's helped me identify a lot of triggers & clues, and has been instrumental in my improvement.
Have you had a sleep study done? Reading your narrative, I couldn't help but think of the possibility of somnambulance or other sleep abherration/anomaly (a college roommate was a rare type of sleepwalker).
Have you asked about/considered hypnotherapy (by a licensed physician
only)?
