Please know that diet, DOES NOT CAUSE extreme fatigue and the symptoms of which you're describing....Also please know that CFS is but a syndrome and is called such because there hasn't been a known CAUSE-UNTIL NOW!
CFS is CAUSED by a combination of bacterial, viral, and fungal infections w/the viral part of it being SO DESTRUCTIVE to your immune system. The virus HHV6 has been found by Dr. JOSE Montoya and microbiologists such as Knox and Carrigan to be the initial cause of CFS.
So after HHV6 is reactivated, you 'collect' infections over time of which your immune system CANNOT fight, even if you drink lots of water, eat organic, go gluten free etc etc etc. In fact food intolerance is but another of many symptoms of the illness.
The bacteria that cause Lyme is only ONE strain of bacteria that invades the body, AND the Lyme bacteria IS ALL OVER THE WORLD, and not just ticks, but fleas, mites, and now they're saying an Asian Lyme strain found in mosquitos...
I suffered needlessly for 10 yrs being misdiagnosed as having G.E.R.D.,allergies, sinusitis, hypothyroidism, and just food intolerance.
The summer of 2014, G.I. doc said NO G.E.R.D., allergist said, "No allergies", cardiologist said, "No heart problems, we don't know why you have heart Palps".....So the MD wrote it all off, the symptoms that is as being caused by hypothyroidism and pre-menopause. The only problem with that was that I'd ALREADY BEEN on thyroid treatment between '10'-'14' & the thyroid replacement drugs weren't working!!!!!!
I went to an ND who specializes in Lyme disease and CFS. She ran all sorts of tests that in the past I actually demanded my MD to do but wouldn't....
I have a myriad of bacterial and virals alongwith heavy metal toxicity and am getting treatment for it which will reverse the thyroid issue and hopefully everything else!
I hope you can get in to see an LLMD OR Lyme literate doctor
