Is some sleep better than no sleep?
If you're starving, is some food better than no food? There you have your answer.
Usually, yes, but of you only get just enough sleep to make you even more tired then no.
NOT if you like having sleep deprivation hallucinations like those pretty flowers that smell SOOO good growing out of your gas stove where the burners USED to be ! I'm just saying....
No, because its always better to fall unconscious.
