You probably had a case of food poisoning. Take an OTC lactobacillus preparation (probiotics) and yoghurt with your meals. Drink plenty of fluids (clear soups, water, ORS in water, 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.
You would need to get examined to rule out a few things such as low blood pressure, postural hypotension (fall in blood pressure, cervical spinal nerve compression, hypoglycemia (low blood sugar), severe anemia, an underactive thyroid (called hypothyroidism), overactive thyroid (called hyperthyroidism), adrenal insufficiency (called Addison's disease), GERD or gastric reflux, and internal ear infections.
