Chocolate will be studied for its fatigue-fighting capabilities in 2016, at Oxford University. This research is focusing on MS-related fatigue and will be interesting to follow. Fatigue affects most of our clients who have neurological injuries and illness. This fatigue is a daily lack of energy; excessive whole-body tiredness not relieved by sleep. Wouldn't it be great if dark chocolate could be an alternative to medications for fatigue?
