Generally speaking, coffee can refresh you, because it contains caffeine, which is a stimulant of the central nervous system and can temporarily drive away drowsiness and restore energy. Caffeine-containing coffee, tea, soft drinks and energy drinks are all very popular, but I haven't heard of lollipops to relieve them. Either there is no caffeine in it at all, or the content is too low. But sugar can still provide some energy. If you want to fight fatigue by eating sugar, even if it is authentic coffee sugar, I guess you have to eat a lot. Don't feel refreshed, your kidneys and teeth can't stand it. I suggest you still drink the four drinks mentioned above.
