Is it exciting to drink red bull? Is it useful to drink in the physical education exam?

Red bull excites your nerves, not your body. Once I drank two cans at night, and I couldn't sleep over and over in bed (I slept well all the time) until 4 o'clock the next morning. But I don't feel how excited and energetic I am, so don't try to improve my physical strength through Red Bull! ! ! I didn't finish the long-distance race that everyone took, but I ran twice. I put in a good word for the PE teacher when I made up the exam, and he was relieved.
