So I love these. I don't recommend starting a caffeine addiction if you do not already have one . However, these 12 ounce pink cans that donate to breast cancer research have become my new best friends. I have always been an avid coffee drinker but prefer something cold and carbonated before a workout as it's more refreshing. They claim to have this thing called Citromax in them which apparently reduces appetite. I think it does reduce appetite but that could also be the 150 mg of caffeine...Regardless they're wonderful. I could climb a freaking wall...and trust me I have a good level of tolerance! :-p oh well. Has anyone else tried these??
