Amino acids can trigger production of other chemicals in your brain. It is common to take the supplements on an empty stomach with water so they do not have to compete with the amino acids in protein in your food for absorption. If you are going to take an amino acid supplement of a specific variety for longer than 1 month, it is better to also take a more general amino acid supplement as well. Some amino acids are essential to your diet and others can be produced by your body as needed. A complete protein - or a combination of proteins to form complete protein - has all the essential amino acids.

In any case, I think your situation is a bit too complicated to even begin to make a guess as to what amino acid or combination of them to suggest. My guess is that most pharmacists and doctors would have a difficult time making suggestions. So if you are going to try amino acids, I think you might just want to consider a general essential amino acid supplement.
