Okay, so I posted before that I'm having a lot of trouble staying awake during my first hour class (and during second and third hour sometimes), and it's still happening, but it seems to be worse. Not only am I tired in the morning, I'm feeling exhausted in the afternoon. I got home from school today and I just wanted to curl up in bed and sleep.

I'm growing a little concerned. It can't be normal to always be this tired, can it?

But that's my question for you. Is this the normal kind of tired that is associated with mental illness? Could it just be that? I take lithium which I know can cause drowsiness, could that be the cause of it too?

Just so everyone knows, my sleep schedule is good. I keep a regular bedtime, though some nights I'm so tired I go to sleep at nine o'clock. It doesn't seem to matter when I sleep or how much I get because I'm always tired anyways.

I just want to better understand this.

Thank in advance for your help!
