I have never tried it but I know it's popular with guys. Well here is a real life warning. Son is 33 and his one friend is as well. Said friend with no family history had a heart attack. A big time red bull drinker. The Dr's all told him that was the cause! I did a lot of dumb things when young that could have killed me, heck I do A LOT of things at 61 that could kill me...certainly a drink isn't one of the things on the list nor worth the stupidity.
