On that note I would like to add that I've cut down my bread consumption over a year ago.

I refuse to eat more than 2 slices a day, unless forced, but never more than 2 slices in 1 sitting.

Why? Because it left me feeling sluggish, which impacted my mood. I would feel morbid and just want to go right to sleep.
I don't like how I feel after 3 slices of bread, its just ick. So I rather make the 2 slices as filling as possible for me.

Listening to my body in this regard has definitly helped me.
I don't have that problem with pasta though, and am always on the lookout for other foods that negatively impact my mood.
