Hi! Welcome to DV! I see you are from Tennessee, yeah! we need some more people from the Volunteer state here!

It sounds to me like you are staying in the borderline state a little longer than is usual for people. It's only happened a few times though, right? I wouldn't worry about it a whole lot.

Have your sleeping habits changed lately? Rearanged your room or changed the time you go to bed at night? Sometimes a change in your environment will cause sleep disturbances.
