"Ultimately, it's all about the calories," he said. "That said, sometimes when people eat a lot at night, they're going to wake up not wanting to eat breakfast."
And that is where the weight gain problems can begin. Also, notes Ayoob, heavy eating at night isn't a good idea because it can prevent you from getting quality rest.
"It's really hard when you've got a meal the size of a basketball under your ribs to go to sleep."
The good news, said Carroll and Vreeman, is that hangovers are completely preventable.
"The most effective way to avoid a hangover is to consume alcohol only in moderation or not at all," they wrote.
Unfortunately, notes Ayoob, most don't want to take that route.
"People want to negotiate with their bodies," he said.
But Carroll and Vreeman looked at a number of supposed cures that have been tested and found that those negotiations seem to always come to a standstill.
They looked at studies for aspirin, bananas and Vegemite and water, and found none of them would prevent the day-after headaches.
Ayoob notes that while moderation is preached, many do not want to follow the guidelines, which limit women to one drink and men to two.
Also, he said, it has almost become a joke when taking medical histories for drinking, as people are reluctant to admit how much they actually consume.
While many refer to themselves as "social drinkers," he said, ""Way too many people are getting way more social."
Ayoob noted that the only way to end a hangover is to wait it out.
"There is no really hard evidence that you can prevent a hangover, except with time and fluids," he said.
The message of these myths, say the authors of the article, is that people should be more inquisitive when they hear these kinds of statements, whether from a parent, teacher or doctor.
"If a doctor doesn't have a good answer, they should go find out why," said Carroll.
"We're trying to illustrate that you should ask why. It's always a good idea to ask why. I guess we're trying to promote a healthy skepticism, especially when it comes to health and medical issues."
