lol....................... i used to drink them, back when i had alot of court dates, and could never sleep the night before... the energy they give you is basicly, caffiene... i'd rather spend the few bucks on the bottle of pills, and get quite a few uses out ofit, then the drink itsself, for the same price and use it just that once...... unless you actually like drinking them, everyone trust me on this..... just save yourself lots of unneeded dolllars and pop two caffiene pillls (about 50 of which come in each bottle) for the same effect... (and i intake caffiene, in Cokes, all day long... so that doesn't matter either, just trust me, if you only look for the energy in the drinks, just take the pills, you'll save yourself lots of money)
