yes. i have been extremly tired and was diagnosed with osa. and using a cpap maching every night almost for a month now. still feeling very tired, faling asleep durning the day at work and such. I dont remember falling asleep at work but when i wake up then i realize that i was sleeping. Tonight I went to the dentist for a cleaning and she took my bp. I have went to this dentist for 40 years, and never mind going in to see them. Tonight though my bp was 203/101. very high. what could be wrong with me?
