I recently found some interesting info re: Taurine, an amino acid that can be missing in the brain or lower in people with neurological disorders with extreme anxiety or stress. I've been taking it at night and was just told I could take more of it without harm.
Severe stress uses up Taurine in our body and it must be replaced. A dose of the powder type is easy to put into water and tasteless or directly on the tongue. My bottle says a dose is 2000 mg. (1/2 tsp.) but I was only using 500 mg. (1/8 tsp.), along with melatonin and other amino acids, as a sleep aid. If I wake up all stressed during the night I take an extra dose of Taurine and feel very able to go back to sleep. I don't see why it couldn't be taken throughout the day as needed which I plan on doing now that I know I won't overdose.
It can be purchased quite inexpensively but I do recommend the powder over capsules and start at 500 mg. and go from there. It can't hurt to talk it over with the doctor and do some online research as well.
Sometimes natural healing can work as good as or better than a drug.
