My best friend’s mother did the same thing...although she also added a drop or two of apple cider vinegar to the baking soda/water mix.
She was near renal failure because of diabetes when she started taking the remedy at the advice of an elderly neighbor lady. About 6 weeks later...she was 100 percent better.
That was 8 years ago.
I take the same remedy for acid reflux...and its gone...along with the zantac.
People with kidney failure aren’t clearing waste from their blood and they get acidosis. Sodium bicarb can help with that.
