Frequent morning vomiting that settles afterward can be due to causes like Gastritis, acid reflux, or an empty stomach irritation. Try eating a light snack before bed, avoid late-night spicy or oily foods, reduce alcohol, and have small frequent meals. Drinking water in the morning and avoiding long gaps without food may help. If it persists, worsens, or is associated with weight loss or severe pain, consult a doctor for proper evaluation.
