dizzy

Do you ever get so tired you get dizzy? I do this thing sometimes, actually frequently, where I'll get stuck reading or using the computer, and I'll be so tired that I want to go to sleep, but I force myself to stay awake, doing more. I get this kind of a dizzy feeling, not like my head's spinning, but like I'll tip if I stand up.

I think I might do it because I often feel like the day has gone by without anything of worth happening. Or, rather, the day has gone by and I don't feel like I've done anything of worth. I think I subconsciously feel that if what I'm doing is not worth much, it shouldn't take up as much time. But, of course, it takes up the same amount of time, which ends up being time lost.

Right now I'm dizzy.
