I was diagnosed with central sleep apnea and prescribed BIPAP. I find it does not help me though and I still wake up with a massive headache,dizzy and freezing cold. I also have some neurologic defects with my brain ( ACC and septo optic dysplasia as well as what they call 'aquired chiari malformation") Does anyone else have central sleep apnea and has anything else other then BIPAP been used with sucsess?
