Clifshots here. I love the Mocha Mocha which has caffeine, the Sonic Strawberry tasted like strawberry jam to me - and it has caffeine also. I did Not like the Cola Buzz....it tasted like a flat gooey Coke! My fav non-caffeinated are Chocolate and Vanilla. ClifShots has the no litter packet where the top stays attached to the packet but I would be very interested in a flask. My hands and Face get sticky from the packets, and then so do my pockets when I stuff the empty packets in them. It might be fun to get a flask and mix caffeinated and non-caffeinated flavors together and then just take a shot whenever.
When I did my century, I ate every hour alternating between enery bars and gel and eating a caffeinated gel every other time. ClifShots uses rice syrup instead of maltodextrin (which can upset my tummy).
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
