Coffee

　I drink coffee every morning, because I don't want to sleep in class.
　

coffee include caffeine. So if I drink a coffee I don't sleep in class.

　

but coffee has a defect. If I drink much coffee. I can't sleep early.

　

drinking much coffee, sometimes is harmful. also It is not good to our

　

health. proper coffee is good. Especially I like Americano coffee, because

　

if has a low calorie. I often go to Japan Zone to drink coffee.
