The Fisher Wallace device stopped working after a few weeks; I've sent it back.
The lyme test came back negative, so one less thing to worry about!
I've been on Terry Wahls' diet for a week. I had started 0.5 LDN at the same time, but then I stopped the LDN so I can first see if the diet affects sleep. I expect to stay on the diet long-term.
I decided to go back to Florida and see Dr. Rey, now that I know I don't have lyme disease. She got me in quickly; I see her on 10/29. Depending on what she says, I hope to start the LDN again after I get back.
