also can get them online...bulk nutrition is a good site
energy..tyrosine and phenylalanine
anxiety and well being...theanine
depression...5htp and SAMe...st johns wort helps many as well tho not an amino acid
for pain problems there are different key aminos
dont forget ur vitamins tho as well...a good B complex, a cal/mag supp at night, a good multi...EmergenC/powdered from walmart was the one for me..it also made me push more fluids and it is good for the immune system....after detox some tend to become ill often for a while...get ur C and zinc
if you scroll down to the right side of the page you'll see the amino acid protocol in the health pages. It'll tell you exactly which ones are best, and you can find them at GNC for sure if you have one nearby, and I'm sure most drugstores would have them too. best of luck to you :)
