Rate your agreement with this statement: I would sleep MORE than I normally do if I could afford to with my work and school responsibilities.

ETA, 21:05 CST Tue 12 Nov 2008: OK, now it's correct. Sorry to all those who responded and commented before; first I forgot to list "tea" in addition to "coffee", and then I added the "sleep deprivation" question and forgot to make the "compounds" question a check box question. This is a repost. Thanks for all your replies!
