I have had C-Pap for three years and also two sleep tests. My settings are Auto pressure max Ipap 21, Epap min 14 with rate of 16. I am extremely tired during the day. I also take Nuvigil 225mg, Wellbutrin, Diovan and Pristyq. My mask seems to fit fine as I do not have leaks and I feel that I sleep good during the night but wake up feeling terrible and it lasting all day. Any help would be appreciated.
