After reading a bunch of posts where it seems like people "brag" about how they get 2-5 hours of sleep per night in medical school, it kind of made me wonder if that's really an effective way of learning the material. I'm just a lowly first year student and I know it'll get 100X harder as I go along, but for the people who are saying they stay up until 4AM studying and then wake up for class at 7, what exactly are you doing during that study time? Reviewing things over and over until they're drilled into your head? Making flashcards? I started out like that as well, getting no sleep. What I found happening was I was falling asleep during lecture, taking a nap when I got home, and in addition to trying to make up for lost sleep, I was remembering NOTHING that I was studying. Let's be truthful - when it's 3:00 in the morning and you've been up 15 hours straight, do you really think you are going to retain any of the info long term, or at least long enough until the exam? So that leads me to my question. Which do you think is more effective: A) Read the chapters/packets once or twice and make an outline, get 7-8 hours of sleep, repeat the next day for the next day's courses or B) Read the chapters/packets 4 or 5 times, get 2-4 hours of sleep. Now I know everyone is different, but I've found I retain a TON more info after a good night of sleep and it doesn't take as much "drilling" if you're well rested. In addition, so many people say lecture is worthless and for some I'm sure it is. But how many people who say that are saying it because they're so damn tired from getting only 3 hours of sleep that they can't stay awake during it? If you sit there and pay attention and understand, it's just one more time that you're seeing the material and it's running through your brain. Just food for thought.
