Warm liquids like tea help to calm your stomach. staying hydrated and getting in some protein is the key.
If you can, make some homemade chicken broth by putting a whole chicken-yes , even the skin-in a pot, cover with water, add carrotts, celery, garlic, dill if you have it. Bring to a boil then simmer for 1 hour. Remove chicken, strain out veggies-sip the broth.
It always works for me.
Hope you feel better.
