I'm having a quick bowl of raisin bran before work! 
Breakfast cereals that are high in wheat bran give me a terrible headache that tastes of metal and make me really tired.
I certainly taste the metals, but it does not give me a headache. Bran is not very digestible for me, though. I burp for an hour or more after eating wheat bran, then, a couple of hours later, I usually begin to fart a lot.
I used to joke to this heavily freckled kid at school that he had been standing too close behind me after I had eaten bran.
:lol:
