I am 17 and drink a lot of caffeine. I drink about 10 cups of coffee (instant) a day and i do get caffeine overdoses ie cramps etc. although i need it in a day to carry on working or i get very tired. Thing is i drink so much of it but then for like 2 days i can give up and i maybe tired but no headaches etc, so am i really addicted? or just genetically immune to caffeine
