I have been using the CPAP for the past week. I start out at 5 and the pressure increases to 12 in 20 minutes. I do sleep alot sounder and my eyes have cleared up. I am having some problems. A couple hours after waking up I start having a mild headache that lasts all day and some light headedness. I have never had these problems before. It's not a blood pressure problem as I moniter my BP and it's okay. Any ideas?
