If you feel that you need a little caffeine to get something done during the day, whether that is from Tea, Coffee, Coke, Lucozade, etc... then the Caffeine Society is right for you!
I don't function too good in the morning without my tea and vitamin C supplements. Also have a cup of coffee mid afternoon, can't have too much though any more gives me a migraine.
Every time I go to the supermarket, I curl my lip in disgust at the "De-Caff" coffee and tea alternatives that sit near our caffeinated fuelled products. I want to smash them to the ground.
