Michelle Farburn began the 75 hard challenge nearly two weeks ago. She followed the rigid guidelines which includes following a strict diet with no alcohol or cheat meals participating in two workouts per day and consuming a gallon of water daily for 75 days. But it landed her in the hospital quote. I think I have water poisoning. Fairborn is convinced her symptoms occurred after gulping down the better half of a gallon too quickly potentially causing the water poisoning. Her blood work appeared normal leaving clinicians scratching their heads.
