Clif bars and others also make a goo type replacement that has caffeine in it so you don't have to try and throw back a pop to make sure you get your daily fix! (I know what you mean about the headache - I have Exactly the same issue) I try to carry a couple of those in case my ride is gonna take me past my noon time caffeine requirement. It replaces the electrolytes And gives me the caffeine. Make sure you check the packaging if you wanna try those - coz they also make non-caffeinated goo.
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!"
