HCL tablets doesn't work, it doesn't have enough Hydrochloric Acid in them, the liquid works (2 drops of the 5% concentration one) on a cup of water with EVERY meal, plus something for liver function, besides probiotics and adding little of cayenne pepper and crushed red pepper to everything, these things works good (it has to be together) for FBO and urine smell and all kind of other smells, it is important not to eat any sugar.
