Peacesoul,
My dr is a conventional trained dr specialised in CFS/ME (I'm in BE, there are no LLMD's here), but all of his patients have to pass a test at US Biotech to determine food allergies, and then pass by a dietist he works with to determine intolerances. It was only after 2,5 years that he discovered the Bart/Lyme, after curing my leaky gut and testing for viruses (like HHV6, HHV7, EBV, mycoplasma, XMRV), trying to boost my immunity (didn't work because of the Bart/Lyme).
My sister had Fibro, she was highly allergic to casein and some other foods - all of her pain is gone since she started the severe elimination diet.
I myself am on a diet to keep my histamine levels as low as possible, low fructose intake and no lactose. It helped a lot.
I would, personally, advice everyone to get tested for food allergies.
But, the diets are not easy to start with. Once started though, I noticed such a big change that I didn't want to go back to what I was eating before.
sorry for entervening into your thread Lymer
