i also contracted Lyme, told i have Fibromyalgia, and sleep apnea.
i believe i have CFS. its this fatigue that is killing me.
i tried the cpap. no go. could NOT sleep with that thing.
then had corrective surgery to enlargen my throat and airway.
still feel the same.
they seem to go hand-in-hand. CFS symptoms say chronic fatigue, pain, and sleep disturbances.
i wish i had an answer for you.. but unfortunately i am in the same position as you.
