Blood Tests tomorrow. Scared i'll faint. Help?

First of all, ask if you can lie down and relax yourself. You feel a little pinch kind of pick in your arm or where ever you are getting it, but if your veins are strong it won't hurt while it is in there and won't hurt coming out. Sometimes they but the needle in and but a little thingy over it and a few little things to get a few tubes, but that doesn't hurt. It really doesn't hurt as much as you think. Also, drink some fizzy drinks maybe some coco cola afterwards, doctors recommend it to put more sugar back to your body after taking blood. I don't know how many tubes they will take, but no one is going to force you to look, you can just close your eyes or concentrate on something else. I remember when I was 11 I had blood taken and the nosy ness nearly killed me and I had to look but it is not so terrible. Good luck!
