If you have sleep apnea and had the sleep study done with the electrodes on your chest and head - this should have showed the sleep apnea. I would imagine the face apparatus is very uncomfortable and if you don't have it, why use it. I think your post describes all your concerns very well and if I were you, I would take it with you to the doctors. I think all your doctors need to consult with each other and figure out what's wrong. I'm leaning to the epilepsy and I think you'll feel better if you're on the right medicine for this problem. Also have the full blood work done as Michah suggested. Do you drink coffee, tea, or coke/pepsi?
