I have had chronic fatigue for 30 years and have spent a small fortune on trying to find a cure. From the result of doing web searches, I realised that my ph was low so set about to correct it.
Cider vinegar and H2O2, as well as being careful with what I eat, have been the means to correct my ph. You need to check your saliva and urine, not just your blood. Blood ph can be good and saliva and urine can be low as a result of the body correcting the blood. Our system knows that the blood needs to be right for our body's sake, so our saliva and urine systems will lower to counteract it. Therefore once we get our saliva and urine neutral things are rosey! Now after 30 years of pain and confusion, I am a different boy!
I have been buying 50% H2O2 solution for spraying crops for insect and fungi control at a 3% mix. I rinse my mouth with straight water and then sip a mouth full of H2O2, hold it in my mouth and swerling it for a minute or so and then swallowing it. I chase it with another sip of water. --don't know why I do that :)
H2O2 works on my crops and has worked on me. Who can argue with that?
