Was looking for some caffeine gum and would up choosing Jolt(20mg caffeine per piece) over Stay Alert (100mg caffeine per piece) based on overwhelming taste reviews for Jolt. Apparently with gum, the caffeine enters your system in 5 minutes as opposed to 20-30 minutes for coffee. Plan on trying it out on those long trail days where its not really possible to stop and brew a cup. Figure I'll keep a pack in the car and throw some in the kits. Anyone tried either one?
