Thanks, this is exactly why I asked for other input. Humans are strange and we can have reactions to almost anything, so I can't rule it all out. But if I can narrow it down, it would surely help. So yes, I have eaten things with flax before, but I've also been sick a lot before. So I think maybe I'll go ahead and eliminate both flax and almond from my diet until I've healed, and then I'll go ahead and experiment with each one to find out which one did it.
