I seem to react very strongly to Zinc but have no theories to why. Any thoughts? It's almost as effective as taking a benzodiazepine. It calms me down, takes away stimulation and relaxes me both physically and mentally. In the beginning I could use it as an sleeping aid. I also got a temporary mood enhancement. The effect doesn't last for long though and it kills my libido. I can add that I suffer from akatisia from my ME. I always feel restless, uncomfortable and on edge.
