I take a multivitamin daily, and i eat enough, and i just looked on Fitday and my iron has been fine all week.
SO, I believe i was dehydrated, because i started drinking lots more water last night and today, didnt have anything with caffeine today, and i feel much, MUCH better. Not fatigued at all. I think not enough water, combined with the heat i was in, was what did it.
Thanks everyone for the replies
