After I saw this article I looked on Amazon to see if I could order it and actually I did. However, I got a stomachache after taking it for the first time. I stopped taking it after that, maybe it was just a coincidence, Idk.

That's because Borax version is extremely high in pH. The stomach is a low PH environment. The borax is most likely disturbing the pH levels causing your stomachache.

Been doing the borax for about 6 months. I do it differently with what I found in a different video (Dr Barbra O;Neil ?) I have a flippy stomach too, so it works great for me. I take a glass pint jar, and put in 1 pinch borax, 1 pinch baking soda, and 1 pinch himilayan salt, shake. 1 drink 1/3 at a time throughout the day. The baking soda lowers the ph. My arthritis is the best it's been in years, and a plus is that my high blood pressure is under control also...down 30 points!!
