The doctor I work with is Dr. Chad Oler, who's contact info can be found here: link. Also, I understand that some may be wary of a ND, but he undoubtedly knows what he is doing with the amino acids and has worked with Dr. Hinz for i think nearly 15 years. If you are interested in scheduling a consult with them just call the phone number on that website and you should be able to get in relatively soon. If you do decide to do that make sure you have all the lab tests and history of what you have done so far organized and ready to go for the consult so you can make sure he is educated on what you have done so far. Again, if you really want to pursue this you really have to work with a doctor who has studied this and had many patients before. Also talking to him and explaining the nausea issue, he would likely be able to identify the problem better than I could and help solve it to move forward.

Backpacker, I think you make some valid points especially with antidepressants, tricyclics, etc. but what these doctors are doing is based on nearly 20 years of research mainly done by Dr. Marty Hinz on using amino acids in combination to obtain competitive inhibition whereby serotonin and dopamine are competing in transport(by the OCT-2 transporter), synthesis(by the AADC enzyme), and metabolism(by MAO and COMT). With the lab tests they are looking at urinary levels of serotonin and dopamine which are not directly interpreted as the levels in the brain because serotonin and dopamine are newly synthesized in the kidneys from tryptophan, 5-htp, tyrosine, and l-dopa. So with this newly synthesized dopamine and serotonin they are looking at how the OCT-2 transporter responds. Honestly it is too complicated to cover in a post on here, but if you are interested in learning more about it read their peer-reviewed papers(which can be found on pubmed or his website neurosupport.com). There are also many videos that can be found on neurosupport.com/videos, that explicitly detail his findings and research and why it works to solve monamine disease states.
