This comment could be written by me a year ago. Only when I drove my caffeine consumption to zero for a whole week (no coffee, no tea, no coke..) I had this massive headache. I am now back to one or two cups of coffee per day, which I enjoy much more.
I'd like to report an experiment I did for the last 12 days; I drank no coffee or tea with caffeine (only rooibos, water and isotone sports drink), didn't notice much except if I smelled coffee I'd feel like "I would enjoy some of that".
Today just had my first cup again, tasted great and no noticeable change then either. I wasn't sure if maybe I'd taken the wrong beans and I had wanted to try a new Ethiopian bean for a different taste and no change then either (well, except maybe that after two cups over 6 hours I didn't really feel like another one).
Maybe I just got lucky (genetically) or it takes a bit more time to feel significant effects.
