If you do decide to keep consuming caffeine regularly just buy cheaper energy drinks than red bull. Mio energy is a good substitute you can simply just add to water and is only $2-3 for 18 drinks. If you're in the South USA check out Parkers Gas stations. They have a good energy drink thats on tap for only 79 cents for a 32 oz drink also. But honestly I think if you were to OD on caffeine youd have to do it intentionally.
