This is my first post, so please excuse any posting errors

I've only recently (within the last month) discovered my two month-long diarrhea (and a myriad of other problems) are caused by gluten. I've cut it out of my diet completely (with the exception of being given beef stew that had beer in it and being told it was gluten-free) for two weeks now. My movements have been regular which is wonderful. However, when I workout, and specifically when I play indoor soccer (short, bursts of speed) I feel extremely nauseous. So much so that I have to take myself out of the game.
I did not feel nauseous when I was eating gluten. I would get stomach cramps and diarrhea, but now that I've cut it out I notice this urge to throw-up when running hard.
Has anyone else had this experience? Do you think this is just due to my stomach "getting used" to being gluten-free? It's really affecting my hard workouts as well.
Any comments are welcome.
Thanks!
