it almost like you are drinking coffee or somethingWww@Answer-Health@Com


Answers:
well number one coffee HAS caffeine in it!. and lots

number two - caffeine doesnt directly stimulate you as much as it clogs receptors in your brain that normally take in chemicals that signal tiredness; what youre doing is essentially preventing your brain from realizing how tired you are!. thats why you get a crash afterwords - youre still tired, you just dont realize it until the drug wears offWww@Answer-Health@Com
