If I dont get any sleep (like I did tonight) I will be fine over 3 days. If I wake up in the middle of the night (before 4) I'm wide awake. Between 5-7, meh....not bad. 8-12.....I am extreamly tired. If I sleep in past one.....I am not getting out of bed unless for food and bodily functions.

Once I had tons o stuff all jam packed (school, drivers ed, tons of homework, daily life just after we got a dog) and got I think a full hour of sleep over 4 days. Worst....week....ever.
