I donated on the 27th of may with fellow user Mickbab, I gave what you would call one unit of blood i guess.
I did not react too well though, after almost 400ml had been taken my vision went really blurry and i almost threw up.
I really want to find out why this was and how I could prevent it from happening if I went again, because it is something i really want to do.
If anyone has an explanation of my reaction it would be appreciated.
I have been thinking maybe blood sugar levels might have been the cause?
Also I am definitely not scared by needles or the sight of blood so this would not be a cause.
Thanks.
