Well, that is PARTLY the case. I realized that during my cutting out norco from my life, I also was a
coke zero junkie....I was so sick, that I only wanted water and gatorade, and NOT coke. I am attributing the withrawal of the large amount of caffeine I was used to consuming to the heachaches I was suffering from and not the norco as today, as soon as I drank one coke zero, headache was GONE!
