I have that problem too! Do you think its the HSC or are we just a sleep starved, insomniac generation?
I barely stay awake in the afternoons, I actually sat on the oval(no one is ever on the oval at my school, I don't know why) in my free period in the sun because I was freezing and I fell asleep...and my ext1 teacher sent another teacher out to check on me becauase from her classroom she could see me and she thought I was some kid that was injured on the oval (I'm rather short)
so that was a little embarassing...although I have thursday and friday of because I just finished my trials so I can catch up on my sleep.
....Tha guy who suggested Red Bull...where can you get that stuff? Like, just in Coles or whatever?
