I would want to measure dietary Taurine levels in the body for a start. Experiments consuming 3g/day have shown no side effects, but your main source is limited to energy drinks so you have to contend with caffeine, and Taurine does not last long in the body (can start to be expelled in urine within 10mins), much like many of the water soluble chemicals classed as vitamins or minerals. Cooking actually destroys it from organ meats and some scientific studies have shown a link between vegetarianism and a variety of mental health issues including OCD. You wont find any substantial levels of Taurine in vegetables, but you will in raw liver, kidneys and brains. From my own experience, 3 or 4 Redbulls a day (1g of Taurine per can) can change many repetitive behaviours. Taurine also has many other positive effects on the body like including VO2 max, improving cholesterol profiles, improving bile acid patterns, reducing depression, improving sleep, improving memory, reducing atherosclerosis, reducing fatty liver disease, reversing some types of cataracts, reducing stones especially in women, to name some of the observed scientific improvements to human health. Its probably why its now added to formula milk for babies since the 80's (but at levels lower than breast milk) and has subsequently improved their cognitive abilities.
