Dude, totally get a food IgG test done. Omg this helped me so much with that. I used alletess, 96 foods for like $85 plus the 5 or 10 bucks for the blood draw. If your having problems with intermitent fatigue and/or neuro/psycho problems I strongly recommend accompanying that with an IgM test. Some say saliva is a better way to test IgM, idk.
