I'm an MSI, and I sleep like 10 hours a day. Maybe more. In fact, I'm so bored most of the time, I sleep just for the hell of it. But a lot of my classmates complain of being sleep-deprived before exams, so maybe I'm an anomaly.
Yeah, just all day OR all night. Seriously though, there is plenty of time for sleep (as much as you need), as well as eating right, working out, seeing friends, and all of life's other pleasures.
Well, I think it's also fair to warn the pre-meds reading this that there is a spectrum of people in med school. Some people can hear something, or read something, a few times, and will retain it. Other people really need to
understand a concept before retaining it. The people in the latter group will, obviously, need more time to study.
If you come into medical school with that ability, you'll probably be fine. If you were one of those people who needed to draw out detailed diagrams, or write out your own summaries before you really understood a lecture, it will be a bit of an adjustment period.
AND I think it's only fair to warn people that if you are one of those people who never go to class, sleep 10 hours a night, and go out every weekend, then third year is going to hit you like a wave of icy-cold water.
Sorry.
Clinical years can find sleep a little less predictable since you're assigned to a team, take call with the team, admit patients with the team, etc.
Unless you go to one of those schools that make even their 4th year surgery sub-interns work
TWELVE hour days.
(Sorry, but that is doing their students, and that field of medicine, a huge disservice.)
I actually found reading for 3rd year to be harder than reading for 1st or 2nd year, but more enjoyable. In 1st and 2nd year, there's always a "right" answer - the "textbook" answer.
In 3rd year, there are TWO "right answers" - the "textbook" answer, and the "real life" answer. You need to know both, one for the shelf exam, and one for your daily life in the hospital. That was kind of annoying.
