I donated blood for the first time today! Ask me anything!
And since I know this question will be asked - yes I did faint when I tried to sit up after the donation. 
= new reply since forum marked as read
...and it was delicious! Thankyou!
The very best type, LOL! 
Blood is one of the products that we have not yet been able to create in a lab, though they are working on it.
Until that day arrives, we need healthy humans to donate theirs.
I used to work for the Red Cross in blood services and so I really understand how vital your donation was!
I hope you will donate again in the future, when you feel ready. Please eat a nice meal beforehand and get some fluids on board too.
I don't say that to brag but to emphasize the fact blood has a shelf life and there is never enough. Plus research suggests that regular blood donations reduce the risk of heart attacks in men, so i thought, 'why not?' 
Remember to drink plenty of liquids - but be sure to avoid alcohol! I've given blood lots of times, but it affects everyone differently. I have a friend who always passes out, just not right away. And I also want to know what your blood type is. Are you the universal donor or the universal recipient? 
BTW, kudos to you!
