They say necessity is the mother of invention. That's why ibuprofen was invented, according to Popular culture has many hangover remedies, "hair of the dog," a greasy breakfast, sweating it out (I don't think so!!). back in the 1960's, Dr. Stewart Adams had a hangover after an evening out with friends. He was scheduled to deliver a speech, so he took 600 mg. of an experimental drug that was being developed as a potential treatment for rheumatoid arthritis. The non steroidal compound, known then as 2-(4-isobutylphenyl) propionic acid, is now known as ibuprofen. In today's world, such behavior by a researcher would be considered wildly insane. Well, it WAS the '60s. My personal favorite is ibuprofen & "hair of the dog," especially bloody marys.
