Karina,
To answer your question on what specific & effective steps to fight acidity, I am not able to be very helpfull as I am not yet convinced anything available without prescription is going to be working.
What RB suggests as well as what you are implementing make sense to me.
What is making me still leery about supplementing with pills such as cesium or high dose potassium pushed by many commercial outfits is the lack of proof, the potential side effects & the debunking of supplers claims in sites such as quakwatch:

Acid/Alkaline Theory of Disease Is Nonsense Gabe Mirkin, M.D.
This article by Dr G. Mirkin is not recent. So, in view of the two recent papers posted at the begining of this thread he might change some of his statements.
The full text of these papers are so technical that only those well versed in biology (not my case) can appreciate the validity of their findings & guess what patients might be able to do to help themselves.
