I have been vomiting now for almost 24 hours. mostly dry heaves or clear mucus or green. I am 69 years old and in good health. I take no medication I am female. I had pizza last evening around 6:30 PM and started to vomit around 10:00PM and reoccurred about every hour all night until this am. I took some ginger ail and started all over again. I have spent the day in bed and just had some small sips of chicken broth and started vomiting again. What do you make of this?
