Hungover Ms. Potato Head -- Did she forget to measure her units?While you're on the lookout for a tipple of the hair of the dog to cure that splitting New Year's headache, here's something else to make you gag: Researchers say the reason ladies like you feel like crap is because you can't do math.

Researchers from the U.K. Department of Health found women drink significantly more than they mean to because, as the Daily Mail so eloquently puts it, "they are hopeless at measuring units." Surprisingly, no Harvard presidents were involved in this study.

The study looked at people pouring their own liquor at home, rather than when ladies were out at a bar. It found women were pouring more than their total daily recommended amount of wine in just one glass.

The English health system's recommended daily limit of wine for women is one glass, but the researchers found the average amount poured at home was 186 ml -- about 2.4 "units" of wine.

The researchers found the men were actually even worse at pouring -- so his math skills suck, too -- but that women couldn't judge their consumption. In other words -- we're fine with telling him to fill 'er up and then guzzling down. Uh-oh, what is wrong with that picture?

Since we already know chicks can do math, how about a New Year's resolution: Learn your limits ladies, and never let him pour your drink. But first, a little hangover cure, courtesy of those boozing Brits.
