On top of extreme cramping you can find your body emptying itself out of both ends if you know what I mean. First time I had it I thought I might just die! Since then I have found a remedy that really works for me. As soon as I think uh-oh I think something I ate musta been off I start drinking cider vinegar diluted in water. I drink as much as I can as quick as I can. This seems to help kill those bugs causing me to get so sick in the first place and once I think I have had enough cider vinegar I have more! It is a strong and unpleasant taste but I have grown to associate it with feeling better.
