Hello and welcome to the forum!
No, it wasn't NAET, but that's one option. Our long time naturopath uses a program called "Advanced Allergy Therapeutics." One thing she was reacting to was her own digestive fluids. Anything she ate bothered her, so she disliked eating in general. So when he treated her for that, she was able to eat without feeling any discomfort. I know this doctor well enough to know that he wouldn't take on a protocol like that without looking into it a lot and observing it being used, so we tried it and have had good success. I like it better than NAET myself. The following describes it, but if you have questions, just ask.
