Is there any way to diagnose it by myself? Is there any way to diagnose any other sleep disorder by myself?
I will try to set an appointment for a sleep lab, but meanwhile I want to get a general idea. Since I'm suffering from excessive daytime sleepiness, I'm wondering whether I might have some sleep issues.
(However, my sleepiness is sudden and happens usually 3-4 hours after I wake up. If I have a sleeping problem it makes sense that I would have woken up tired from the start, no?)
