Post Roller Coaster Syndrome

An occurrence of feeling blues/depressed or withdrawals proceeding the days after going to an amusement park. Usually during this time you constantly reminisce or have a strong urge of going back.

Homie A: So how was your day at Six Flags?

Homie B: It was sooo fun but I really want to go back now. I think I have Post Roller Coaster Syndrome.
