For those of you in college, is "burn out" a real thing? How the fuck do people study all day long every single day and not get mentally drained? Everytime I try to go on study binges, the absolute most I can do is 5-6 hours even with breaks. And then, after a few days I can't study at all. Like today, for whatever reason I've been feeling like shit and can't mentally focus on anything, and I have an exam tomorrow. This same exact thing happen to me last week too.

How do I stop this? I'm thinking about cutting out daily coffee, because I'm starting to think that's what causing this. Do I maybe need to sleep more? I dont exercise at all and I smoke cigs/drink on the weekend. I do also have a shit ton of assignments I need to do, but I'm not sure if that's playing a factor here or not.
