...so you have no idea whether it's from cutting out caffeine or gluten. Great way to not understand your body! Try going on a seitan rich diet for a week (it's basically pure gluten made to taste like meat, and actually tastes quite good: http://en.wikipedia.org/wiki/Wheat_gluten_(food) http://en.wikipedia.org/wiki/Wheat_gluten_(food)) - if you actually feel any worse (more than the nocebo effect), then you might really have a gluten problem. If you feel better, then the problem was most likely the coffee (or some other ingredient of the gluten containing foods you were eating, in which case you better of on no-gluten, so you'll need a further experiment to clarify this). Experimenting on your body is cool, trust me (yeah, it's boring compared to doing it with some hard drugs or psychedelics, buy still sciency and fun :) )
