So have been taking this for a few weeks, I have noticed better endurance but I am also noticing signs of hypoglycemia. Recently I have had flashes of light in the corner of my eye. It has only happened twice but both times freaked me out. I googled quite a bit, one possible cause being retinal detachment yet retinal detachment would be like lighting bolts where as my flashes are thick horizontal lines of white light. Today it was accompanied by pressure behind my ears, similar to that of going up a mountain or diving. I do not currently have medical insurance as I am living on my own at 20 but am wondering if this has happened to anyone before.
It may also just be the spirodex I have causing a weird fluctuation of epinephrine.
