I donated blood at work this afternoon.... I guess the multi-vitamins are doing good since my iron wasn't too low this time. I gave once before and it was no big deal other than the fact that I seem to have really S-L-O-W blood... two people came, gave and went before I was done filling my bag! This time I got woozy and felt sick to my stomach, which I didn't expect. But I got this t-shirt! I'm ok now though and back at work.
