Anyone else’s study habits disgusting post-MCAT

Before the MCAT I’d study like 4-7 days in advance for most of my difficult tests. Now after the test I procrastinate all the way until the day before tests. I keep telling myself I will stop but I don’t. Anyone else dealing with this? I’ve got a friend in the same boat. Not doing bad on my tests or anything but I just have to stay up all night
