Ill try and make it. If i donate blood I'd have to bring my wife cause I have this cool ability when I donate blood I pass out
.
I have the same ability! First two times I donated, I passed out on my way to the snack station after it was over. The second time, one of the guys suggested that I lay flat and elevate my feet while I donate instead of sitting up. I haven't had a hint of an issue since, and I'm one donation away from 5 gallons now.

Just an idea to try, if you don't already! When they ask which arm to use, I tell them and then add on, "And you'll want to lay me flat--trust me, we'll both be happier." Never been an issue!
