vitamins
I am not a person who believes all kind of medicines. Before 30, I barely went to see doctor or took any kind of medicine. After 30, my health is becoming strange, maybe because I was not doing so much sports now or began to go to see some doctor.
normal I think, when the medicine does not fit your body, so it will not work out for you. or sometime when you took the medicine, and then you felt a little bit better, but it would make your other parts of your body get messed up. For example, you took some vitamins, but it makes it difficult for you to poo out. Or sometime the medicines just kill you.
Taking medicine is really a frustrating thing.
