My husband was diagnosed with Central Sleep Apnea. He has been to 5 Repiratory Specialists, 7 neurologists, tried CPAP, now on BiPap. Long story short -- the Bi-Pap isn't working. He is falling asleep behind the wheel and at work, incoherent, etc. Oh...he is also an insomniac, has chronic migraines, chronic pain, and is on 10 medications. Needless to say, we have no life anymore.
