I know that Chronic Lyme is a persistent infection of the CNS (central nerveous system), and that my 21 year old daughter's sleep disorder (unrefreshed and also severe circadian rythym shifting over weeks, months, etc) is related to it. Over the years, she has not found any supplements to be helpful for sleep. Any of the meds recommended by the LLMD, she refuses to try because she always has bad reactions to meds. Any advice?? I am concerned, because I know how important sleep is to the healing process. Gradually she is also showing signs of S.A.D. (seasonal affective disorder) too, which I believe is also neurological. So I asked our integrative doctor what Light therapy machine to get. He sent a letter with this information, so we could use this to see if insurance will pay for it. Otherwise the office manager said the full-spectrum ones available at a local store for $30 should work. Does anyone else here have S.A.D.? Did insurance pay for your machine? And do you recommend a certain machine? Thanks for your advice!
