Have you ever fainted/passed out?

I have twice. The first was when I was in my early teens I think. I had to get some blood work done and I can't remember how many samples they took, but it was a lot. I blacked out/fainted but I'm not sure if it was from the blood being taken or me just freaking out about it. The other time was really my stupid fault. I had worked all night without sleep, then I was drinking and getting high with a friend in the morning after having given blood. I remember telling my friend that I was really high and then I passed out.
