I'm either starting to develop one or I'm simply not drinking enough other liquids. In any case I start getting head aches around three or four in the afternoon unless I've had my usual half liter of green tea. Maybe it's time to pick another drink of choice, but most other bottled drinks (and I'm not counting water, if I want that I'll just go and fill an old tea bottle from the tap) contain sugar instead of caffeine to wake you up. Not that I have anything against sugar, but getting it in a drink removes the need for candy, and then where would we be? On the way to overweight? Quite possible.
So I guess I'll keep with the tea. Green tea is supposed to be good against some kinds of cancer, something that I doubt can be said about most sodas. Besides, the coop at Katahira now has little cell phone ornaments attached to the bottles of my preferred brand. If this keeps up it won't be long before I've collected them all and/or start getting doubles. In absence of a cell phone I'm hanging them on my pda (only three so far).
