I'm here, obviously because I'm experiencing some of what is being discussed.
First, I will try Grapefruit Seed Extract (Nutribiotic) to kill any bacteria as well as parasites. Then, start a regimen of Acidopholus (the good bacteria).
To settle your stomach, try getting some ginger root from the grocery store, grate some in a pot, put some water, make it come to a slow boil, simmer, drink it down. You could add some Stevia (natural sweetner) to it.
I'm hoping my digestive tract is just off a little and will return to normal.
Also, try increasing fiber...drink the stuff out of the can if you have to. As long as it has psyllium husks (main ingredient in fiber drinks).
Hope this helps.
