My skin is out of control all of a sudden. Think all the diet pepsi I drink has anything to do with it?

Absolutely. The acidity of the sodas at a pH of 2 represents 100, 000 times the number of hydrogen ions of water. This shuts down all of the enzymes systems of the body and intereferes with toxin removal from the body. Secondary removal of toxins is through the skin and this causes skin irrititation. Challenge: stop the sodas and other acids for 30 days and see the difference.
