So you tossed back one too many and now you're suffering. It's a classic hangover.
Alka Seltzer has been a favorite cure for years. Researchers in South Korea say asparagus can help you recover after a night of drinking. A brand new product sold on the internet called "Blowfish" combines aspirin and caffeine for promised relief.
Dr. Michael Oshinsky studies hangover headaches. He says the first thing a person who has overindulged should do is drink water, because too much alcohol is dehydrating. After that he suggests any pain killer that's a non-steroidal anti-inflammatory.
"Ibuprofen or Aspirin would be a good idea," he says.
He also says a cup of coffee can help. Dr. Oshinsky says his research on rats finds when you take the painkiller matters. Take it right away after drinking if you've only had a little, but if you've had more to drink, wait a bit.
"If a person drinks a small amount of alcohol than the headache will come sooner," he explains.
"Four to six hours later where there is this peak to the breakdown product acetate which causes the headache, that's when you need to take the NSAID along with the caffeine."
Finally, alcohol puts a strain on the liver, so it's important to avoid painkillers containing Acetaminophen, which is metabolized by the liver.
"A person shouldn't drink and take acetaminophen after. It's a potentially toxic combination," Dr Oshinsky warns.
