Yea, having too much really isn't good for ya, and I recognize that, but in the work place and at school, it's free. It's like water during the morning time. All you have to do is walk up, grab a cup and pour. They even have the sugar and cream there for ya if you want it. If you're looking for a fix to get you through the morning, it's hard to avoid free.
On the flip-side, I feel as though I'm painting myself a caffeine addict

-Which I'm nothing of the sort, I don't drink it every day, and often go a week or two without touching a cup. During the summer however, I do admit, it's an everyday thing, but school is much different. Sometimes I can get away with scheduling a not-so-early class, and be better for it without the induced stimulants in the morning.
But in architecture we are quite often pulling all-nighters every day (towards the last 5 weeks of the quarter (a.k.a. Semester) With 2-3 hour naps during the day. I'm sure anyone who's studied architecture can testify. Some resort to coffee, and others, go take a shower, and then there's some like me, that buy up the whole box of energy drinks to last them the whole quarter. It's pretty much an un-listed material fee for getting your projects done. The longest I've pulled without sleeping a wink consecutively was 4 days (3 all-nighters). I literally worked around the clock, stopping only for food and toilet. I had to skip 4 of my classes over the course of those 4 days. It was extremely intense, and I'll never do it again. I got an A in the project though, so I thought it was worth it.
And because we work the long nights up there quite often, we've developed a kind of "Studio Culture" which as part of one of my architecture theory classes, we were asked to somehow document this phenomena. So, we organized ourselves to go shoot video of each student-year working and interview students and teachers.
Ultimately, I was the only one with video editing experience, so I put everything together for an 18 minute documentary about this "studio culture" And it really helps to explain what I'm talking about with the all-nighters and commitment to the study. I recently uploaded it, so you guys can view it on Vimeo.com!
