New York City Syndrome 

The tendency of a New York City resident to only judge other cities by how they compare to New York. By living in the largest grid city in their country, other cities, in comparison, seem small, spread out, slow-paced, too quiet, poorly planned, or just not like cities at all.

Friend: "So how do you like Boston so far?"
NYC Resident: "It's a quaint town, but I'm not a fan, it's just an older, smaller, less-populated NYC."
Friend: "Dude you've been living in Manhattan for five months, you can't have New York City Syndrome already."

Friend: "Look at this instagram video of Shinjuku, Tokyo, the streets look so calm and narrow with little shops and ramen places scattered around. I wanna visit so badly."
NYC Resident: "Aww yeah! It's like a tiny little New York. A cute mini city!"
Friend: "Bro Toyko is the largest city in the world, can you quit it with the condescending NYC Syndrome?"

New York recovery syndrome 

A strong feeling of exhaustion on the day after (or sometimes up to several days following) a day trip to a city several hours from home.

Akin to jet lag, symptoms appear because such a trip often requires waking up earlier than one is accustomed to, spending many hours of the day seated in a car, bus, or train, sometimes as the driver, and going to sleep later than one is accustomed to.

The symptoms include fatigue, weakness, laziness, and a lack of enthusiasm. The sufferer may not necessarily feel the need to sleep during the day, but won't feel very energetic either.

While the term can apply to such travel to and from anywhere, it is named by people who live in cities several hours from New York City from where there are direct highways and regular bus and train service (such as Baltimore, Boston, Philadelphia, or Washington) who take day trips to New York for business or pleasure and return on the same day.

I am taking off from work today because I have New York recovery syndrome.
