How much is my brain damaged if i have been addicated to caffeine for 10 years? ex. i drink energy drinks and pop on a daily basis if i don't i can't think or wake up

Probably no damage: It is conceivable that extraordinary quantities of caffeine could produce brain damage, but not likely. Excessive use or "addiction" may cause problems, even possible brain changes, but these would not be classified as "damage." You may be painting a picture of addiction, not actual damage -- this could be better addressed by a professional evaluation.
