Don't worry if you sip too much bubbly at tonight's New Year's Eve party…Gwyneth Paltrow's got you covered!
The actress shared her best hangover cures just in time for the holiday with subscribers of her GOOP email newsletter this week.
"We all know what happens on NYE so here is our best to help you prepare for the day after," she wrote, citing medical advice from professionals including Dr. Frank Lipman and Dr. Oz Garcia.
One of the 39-year-old star's top tips? Try a Mercy health elixir, which Paltrow -- an investor in the company -- claims is "packed with amino acids, vitamins, minerals and herbs that protect your system against the inevitable hangover and that flush you can get from drinking."
Paltrow also suggests hydrotherapy after a long night out. "If you have the time and the inclination, I've found that the best hangover remedy can be a hot and cold spa treatment," she writes.
"I've been known to recreate this experience at home too. Just draw a bath that is as hot as you can handle it and mix in some Epsom Salts and Baking Soda," she continued. "Soak for twenty minutes and then pop into a freezing cold shower for 1 minute. Get back in the hot bath and stay until you're warmed up. Then get back in the shower for 1 more minute."
While Paltrow fully endorsed the steam room idea, Dr. Michael Lucchesi of New York's SUNY Downstate Medical Center tells the New York Daily News her remedy is too far-fetched to be effective.
"Alcohol is a diuretic," he told the paper. "Why would you want to engage in an activity that would cause you lose more water and salt?"
Still, Dr. Lucchesi was able to support a few of the A-lister's tried and true hangover cures, like downing plenty of water, taking Tylenol and -- when all else fails -- crawling back into bed to sleep it off.
