what happens when you lack sleep

i'm exhausted... can't do many more of these late nights... feels like i'm in college again... too much work to do, not enough time to do it ... slave driving managers ... want something now, this is an emergency! ... my "normal" now is to work 9-5:30, make dinner/play with kids/put kids to bed until 8, then back to work from 8-2a... when will it end?

on the bright side... in my half-asleep/half-wakefulness this morning, i hear belly singing, "what do you want from me? what do you want from me?"

then this conversation ensues:
b: mommy are you tired?
m: mmm hmmm.
b: are you really really really really really tired?
m: yes.
b: but you have to work.
m: no it's ok.
b: but you have to, ok? because you have a lot of work.
m: but i'm tired.
b: but you have to work so you can get money.
