Hello
I appreciate your concern
Looking at your description this could be food poisoning or gut infection either viral bacteria or protozoa
another possibility is alcohol induced gastritis.
your symptoms can be caused by
nutritional deficiency or electrolyte disorder owing to diarrhea and vomiting
I would like further information to guide you better like
relevant medical history
Is it associated with pain in abdomen or vomiting?
since how long you have this problem
Have adequate fluid intake including ORS or fruit juice to avoid
dehydration and electrolytic imbalances, You may require a course of antibiotics under supervision of your doctor
Pantoprazole or
rabeprazole with antacids as an antiacidity medicines are advisable.
Meanwhile have probiotics, curd, yogurt or banana as a home remedy
Since I can't physically examine you to get more clues so In my opinion you should see a doctor for clinical and per
rectal examination to confirm the diagnosis
Hope this helps you
Please write back to me with all the details I will definitely help you in best possible way
