I'm not sure if this is the best place, but I guess it's loosely related so here goes, For the past approximately 5 months I jolt awake anywhere from 2:45 am to 4:15am, every night, with the exception of maybe 2 to 4 nights, when I was possibly too tired to recall waking up. But it's always in between those times and I'm always jolted awake and feel like I'm wide awake, like I've slept a full night even when I've only been asleep some nights for like an hour. I don't know what's causing this, there are no other details about the waking that are consistent that I have noticed.

I have some suspicions, but I would love to hear some of your opinions.
