Students' Sunday Night Syndrome is one of a student's most common anxieties. It's the feeling when you are sure you have no homework, but you are suspicious that you missed something or forgot an assignment. You feel free, but also a nagging anxiety that you're going to have to stay up late on the Sunday Night and work on it when you remember.
Students' Sunday Night Syndrome is often one of the symptoms of hardcore procrastinators.
Most of us with Sunday Night Syndrome react with sleeplessness or we just don't give a fuck and prepare for Monday Morning Homeroom Syndrome.
