In a word, YES
You are abusing the beverage to keep you awake/focused/whatever. There have been rare cases of death from excess energy drink intake.
At 23, if otherwise healthy, there is no reason to require this kind of stimulation, try switching all but 2/day (max) to caffineated soda, and then start swapping them out for decaf or water. If you can't stay awake/focused once "detoxed" then see a doctor.
