A new exhibit offers five easy steps to make the big nights, and the mornings after, a little less painful.

Top of the list is to take plenty of vitamin B6 during and after drinking. It is known to reduce hangover severity by as much as 50 percent, although the museum says nobody knows why.

Next is a sports drink laced with extra sweeteners to round off the night to help replace lost body sugar.

The museum suggests sticking to vodka and gin if spirits are your tipple the clearer the drink the fewer impurities, such as methanol, there are.

"When it comes to hangovers, methanol is the villain of the piece,"it said in a statement.

Eating while drinking slows down the rate at which alcohol is absorbed by your body, and drinking water throughout the evening stops your internal organs from shrinking.

"A slightly shrunken brain is a well-known side-effect of drinking,"the museum said.
