Question: How can my diet help prevent or relieve cyclic vomiting syndrome?

Your doctor may recommend coenzyme Q10, levocarnitine (L-carnitine), or riboflavin as dietary supplements to help prevent episodes.
Question: What should I eat and drink if I have cyclic vomiting syndrome?
Answer: When your nausea and vomiting stop, you can generally go back to your regular diet right away. In some cases, you may want to start with clear liquids and go slowly back to your regular diet. You should eat well-balanced and nutritious meals between your episodes. Your doctors will recommend that you not skip meals in between episodes. If you are dehydrated, drink plenty of liquids that contain glucose and electrolytes, such as

broths
caffeine-free soft drinks
fruit juices
sports drinks
oral rehydration solutions, such as Pedialyte
Question: What should I avoid eating if I have cyclic vomiting syndrome?
Answer: In between episodes, you should avoid eating foods that may have triggered past episodes. Eating certain foods such as chocolate, cheese, and foods with monosodium glutamate (MSG), may trigger an episode in some people. Adults should avoid drinking alcohol.
