Hydrogen Peroxide 3% works wonders for me. I used one cap size of HP (the cap on the hp bottle) and one cap of bottle spring water. I simply tossed the hp/water solution in my mouth and swallowed it. I did this three times a day for one day only. I had eaten some food that had badly upset my stomach (my stomach kept making rumbling noises)and it was cramping up so badly. the same day I immediately swallowed 1 cap full of hp and one cap full of spring water (hold the cap of hp in your mouth then chase it down with the capful of spring water). That same night I sleep like a baby and I felt so good in the morning. I hope that you have the same experience because food poisoning is never a good thing but quick relief is a miracle. I took this mixture immediately after my stomach started cramping.
