Is someone getting the best of you?

No one's getting the best of me.
But this depression is.
I feel better, I really do.. I think all the hormones from AF was pulling me down in the last few weeks.
But I'm exhausted... and thats getting the best of me.

On Thursday night, I got around 6 and a half hours sleep.
Thats not bad, previously that would have been MORE than enough to carry me through.
But no..
I fell asleep at 7:30pm, woke up at 3:30am.
= 8 hours
Went back to sleep from 6:30am until 11:30am
= 5 hours
I didn't do a whole heap on Saturday.. I watched some movies.. Didn't burn a whole heap of energy.
Saturday night I went to bed at about 2:30am
I woke up at 9:30am
= 7 hours

By 3:30pm today I was exhausted again, I slept from 3:30 too 7:30pm
= 4 hours

Thats a total of 24 Hours Sleep in just over 48 hours.
I'm not really sad.. but this is killing me.
As much as I love sleep, is totally making me feel useless.
My gut is telling me, maybe I need to change medications.
But this one.. as hard as it is.. its working.
I don't know if I really want to risk something that might have worse side affects, or might make me worse.

Maybe I'd be able to make a decison.
If I can just stay awake.
