If you need an energy drink to get through a school day, you've got some serious problems
Anywho, I never found Monsters effective, but I think they taste good. May have been something else though.
That's pretty much like saying "if you need a coffee to keep you going through the day, you've got problems," since the effects are quite similar, if not identical.
Anyways, yeah, that sure is a huge ass monster. One night out with friends I bought myself one of them and it definetely made a difference.. that night was spent mostly walking around town and toking up.. usually that kind of combo would have me incredibly tired after 2-3 hours, but that monster totally kept me going all night.
