I have only do it twice but I love to give blood. The first time I got dizzy (maybe from needle nervousness) and this last time my blood pressure went from 120/68 to 90/68 and I felt fine. The phlebotomists where kind of worried. My iron is a little low but apparently not low enough to not donate (the lady asked me if I ate red meat, I said no than if I ate greens and I eat a ton). Do you think it would be safe for me to keep giving blood?
