If you've eaten at one of your favorite greasy spoons and you feel really sick and want to vomit or otherwise. I suggest you take a tablespoon of organic apple cider vinegar added to a cup of water and drink down quickly. Wait 10 minutes and repeat process. If you vomit, that's probably a good thing, you've then expelled the vile that made you feel so awful. You may take this remedy before eating out and eliminate getting sick altogether. It works for me.
