my 6 year old is throwing up (sometime projectile) and complains of pain in his stomach for 4 days. Eating BRAT diet but still throws up. No food particles coming up - only fluid that is green and cloudy. Once he throws up, he is fine. Have him on 15 mg. Lansoprazole. No fever, stool is normal (no diarhea). 6 yrs old, 45 lbs, 46 inches tall
