Unhealthy studying

I started to study too late. I like international economics, but don't have enough time to study for it. The exam is tomorrow.

I have some really unhealthy habits when I study. I eat a lot. Food and snacks get me to sit down by a table and study. It's bad and stupid, but I prefer gaining some weight during exam weeks, than failing all courses. Today I have eaten a lot of french fries and tiger ice cream. Coffee is also a good thing for studying. And water, a lot of water. And sleep. Will go and try to sleep now, to get up early in the morning and learn all things by heart and forget them after the exam. Smart. The system with exams is so great. Not.
