I know of two cases where high protein low fat low carb diets caused kidney damage. Don't go there.
Here's, what I would do to start. For $120, get the Alex Pack and for a month saturate you body with all 90 essential nutrients plus Sweeteeze
If you still have any stubborn symptoms you'll be nutritionally sufficient and ready to begin targeting them.
B2 Riboflavin (in Alex Pack)\
Sore mouth. Lips, tongue
Youngetivity has Selium 90 gelcaps also if these ring true.
Signs of Selenium Deficiency:
Cardiomyopathy (Heart Attack)
Sudden Infant Death Syndrome(SIDS)
Age spots, liver spots
Myalgia (muscle pain and weakness)
Anemia (RBC fragility)
Does that make sense? Verify that you can't be missing anything by taking enough of every thing essential.
In a month this could be well on it's way to being resolves. Let me know.
Free includes debt-free!
