as per my knowledge vomiting after excitation has nothing to do with GB syndrome, it may be due to anxiety, stress or over-excitement. anyway whatever may be the reason here are few tips to cope with it....
- Do breathing exercise. Close your eyes and take a deep breath, then another. Let each breath out slowly. Repeat as needed.
- Do regular exercise. Walking and stretching can soothe a stressed-out body or an over-excited mind.
- Do meditation.
- Eat and drink rightly. Peppermint tea or ginger soothe a nervous stomach or nausea. Also, stay hydrated.
- Take adequate rest. Take naps and always get a good night sleep.
