Stress is a strong builder of acidity of tissues and fluids, Can't go on.

I squeeze two lemons into about 8 oz of water and drink it. If I'm not
better in 4 hours, I repeat the process. Usually, that's sufficient to calm
the feeling tone strongly.

The principle behind this is that the lemon, while it is high in citric acid,
is transformed in digestion into a very strong alkaline ash (or residue).
That helps to relieve the symptoms of excessive acidity and is very
helpful on occasion.

You might try it; it does work for some of us.
