It’s my first priority to serve you.
Thanks for providing more information.
Well as you describe, most probably it's due to violently vomiting.
However it's good to take OTC Gaviscon.
Also hydrate yourself with cool water.
Avoid hot,spicy,fried food,carbonated beverages,alcohol,smoking for a while.
You should eat semi-solid food.
If you have persistent vomiting,blood,pain abdomen then you should visit ER to rule out gastrointestinal bleeding.
Otherwise you'll be fine.
If you have any further query then we can discuss it thoroughly rather than give us poor/bad service.
We are here to help you until you satisfy.
Bonus and positive feedback are highly appreciated.
