“What to eat after vomiting caused by over-eating pasta and lettuce salad with toast and warm rice and milk?”

I am a 93 year old female, ambulatory w/o cane. No dementia. Live at home in a private suite of rooms, self-isolated because of Covid-19. Have Asthma and Afib and high blood pressure and take Alvesco Inhaler, Coumadin, Metoprolo and Lisinopril. Also Magnesium supplement. Overate last night and vomited about 18 hours ago. Have not ingested any food or water. Food available at home: Real Ginger Ale Caffeine-free, soda crackers, wheat bread, and Protein Shake (Vanilla Milk Shake). I am ready to take sips of water and the liquids and/or foods you suggest. I have homemade chicken soup with many nutritious vegetables.
