2 times in a row just after eating could be because of a metabolic disturbance as well. You need to avoid high carbohydrate
diet as it can cause a similar picture. Better to get your blood sugar tested. If you were having sweating, trembling and disturbed vision as well. This could also point to a heart rhythm abnormality as well which should not be ignored. Get an ECG to confirm. Consult your Doctor and explain the incident and get examined and required testing.
