Whenever I've been bad (hamburger, chocolate, and such), I wait about an hour or more after eating; then I take 1/4 teaspoon of baking soda in a glass of water. That helps to bring my pH back up.
I sometimes test my first urine in the mornings. I never test my saliva anymore. It always has higher pH than the urine. I don't trust it.
