If this started recently then drink plenty of fluids (clear soups, <span style = 'background-color: #dae8f4'>water</span>
, ORS in <span style = 'background-color: #dae8f4'>water</span>
, lemonade). Eat light, do not stay hungry but eat simple things like
toast, porridge, cereals, crackers, banana, rice, peeled apple, etc. Take over the counter antacid and
antiemetic (this SOS for vomiting
). Watch out for a day or two with this treatment.
If still the symptoms persist, then you may need an antibiotic for the gut and
would need to see a doctor.
