Reflection on real life (Unit 3 Task 2)

Since secondary school, falling asleep in the classes and lectures have been a problem to me for many years. I just cannot seem to focus throughout the entire lesson. This makes me to miss some information during lectures or classes. Then, I have to do self study at home to learn what was being taught, which resulting in spending more time.

I have tried many ways to prevent myself from dreaming in the class, for examples, drinking a lot of water, sleeping early at night or eating sweets, but this problem still exists sometimes.
