Sleep is for the Weak

I'm exhausted.  I always say this but I think it's finally really catching up to me.  I'm so tired that I can't sleep anymore.  I lay in bed until close to midnight and wake up at 5:30 or 6am.  Even if I go to bed a bit earlier, I just wake up and then I can't fall back asleep.  Maybe I'm just going through some adjustment period or something.
