Hi, I am not sure if I can be of help to you or not. I too have been recently diagnosed with central sleep apnea, I also have Fibromyalgia and am on 2ltrs O2 at night with Cpap but am waiting to have more sleep studies done. My Dr. is suggesting a Bipap with O2. I am still feeling weak and very ill with body aches and headaches about 80 % of each day. I would be very interested in speaking with you to see if we could compare notes. I have had no luck in getting any info on central sleep apnea only on obstructive which doesn't apply to either of our cases.
