Regarding the accuracy of fitbits…I recently had a Video Electro Encephalogram (VEEG), while I thought I got 6 hours of sleep the VEEG and the Doctor said 3 hours of restless sleep if that. When I was using my Fitbit it said pretty much the same thing and I discarded it because I was sure I had 6 or more.
I also had a memory test which a neuropsychologist read and confirmed the fitbit readings…he hadn't seen one that bad in years. I am on CPAP too.
Are you guys sure you are getting good sleep? Maybe your fitbits are right too?
I have a sleep study scheduled in which I will be taking a hard look at my CPAP settings and machine.
