I just figured out why the Cool Mint Chocolate CLIF bars are the only ones I like: they're caffeinated! Says so right on the front of the package. I looked at their website and it turns out Cool Mint Chocolate and Peanut Toffee Buzz are the only two flavors that contain caffeine. It got me wondering if anybody here packs caffeine supplements. I usually avoid addictive substances but anything goes in an emergency. Does anyone here use 5-Hour Energy shots or those sketchy caffeine pills that I see at gas stations?
