Well, I just guessed '8'. I don't want to sit up all night since I had ZERO sleep last night, and I'm feeling very sleepy and tired even though I haven't even taken my pills yet - I have chronic sleep-problems and usually don't feel tired without these pills, so that I do right now says something about how little I've been sleeping the last few days
So, good luck to the rest of you. I look forward to seeing the answer next week since I can't see anything else it could be =) see ya then!
