screwed up

my sleeping pattern is horribly screwed up.
like seriously.
say, i sleep at 1am.
i wake up at 2.41am.
i wake up at 5.32am.
and i finally got up at 10.50am, because i was so bloody pissed with myself that i cant even get proper sleep.
this is shit la sia.
I cant even sleep through the night these days, even though i'm still under medication.
