You should check your Heavy Metals Toxicity levels!!
I have Mercury Poisoning and it totally depleted all my alkaline. No matter what i do, eat, drink, nothing will help raise it.
I will be having my 35 year old cracked and leaking Amalgam fillings removed in 3 weeks. Then I will do a heavy metal detox and a Baking Soda/Molassas pH balance protocol to restore health.
I will write back with the results, but in the meantime I know for a fact, heavy metals DO make you acidic!! So check your toxicity levels. Do you have Amalgam fillings?
