This morning I felt a pain that needed a medicine. Few minutes after eating my breakfast, I experienced a gastric pain that was intense that I took a Buscopan Plus tablet. It was accompanied by a diarrhea in which I spent more time in the rest room.
Then, I realized that I stayed late and slept around 2am, which came to a further realization that I did not eat a midnight snacks/meal. This was the advise that was given to me by my doctors that if and when I stay late, I must eat.
