GLUTEN

As much as I LOVE bread, and especially with butter on it, I have found that eating gluten causes all sorts of issues with me, namely this list--

sinus issues
watery eyes
bloating
depression
weight gain
ravenous appetite
foggy thinking
tiredness

What makes it difficult to pin down is that it is hard to equate gluten to these symptoms as they come on at different times, and not immediately after eating gluten.
