Step one should be obtaining a Comprehensive Stool Analysis and a sensitivity screen for the results from the Great Smokies Diagnostic Lab to make sure just what you are suffering from and what the extent is of your dysbiosis. You will be money and time ahead in the long run. Shotgunning is a good way to burn up money and time and to frustrate yourself. These problems are seldom due to one organism only, yet the symptoms can be similar because there ae only so many ways that an organic system can respond to any infectious threat. Candida alone has 55 or more strains with an assortment of sensitivities hence what works for one strain, will not necessarily work for the other and so the symptoms may persist on any given treatment regimen unless the sensitivities of all strains present are known and accounted for all at the same time. Good luck.
