We are wanting to use Melatonin for a calming agent. On other posts, I had seen people recommending that grow and shine stuff (when using melatonin for hair) and also Omegatin (from tractor supply). Do either one of those work for calming too? the first show is this weekend so needing a fast acting something this time, next show is the end of july/first of august. Other then the Melatonin pills from walmart what do you guys recommend?
