I recently had these symptoms: bad headache, dizzy and light headed, sweating then vomiting. it lasted about 2 hours and after i vomited i felt better?

? Food poisoning: Sounds like food poisoning. If symptoms do not recur, you may just wish to make a note of what you are before the vomiting and avoid that. If symptoms recur it would be prudent to see a doctor. Wish you good health! For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
