Blood Donor

I gave blood last Wednesday.
It was something I'd always wanted to do but I'd just never got round to it.
When I saw the poster up in my work I signed up for it.
I got to the blood truck thing and waited for about an hour in the queue. The people running the truck couldn't have been nicer mind you. I got the the little thumb prick test which made me jump!
Then I got taken to one of the bed things and told to lie down. All the medical gubbins was set up and we were off!
A mere 5 minutes later and I was finished. The lady took all the tubes and stuff away and gave me a bit of cotton wool to hold on to my arm.
"Lie there for 5 minutes and then you can go." she said.
5 minutes passed, when she came back she asked me if I was ok as she took away my pillow, turned the fan on and made me raise my knees.
I felt absolutely fine but she said I was really pale. After 5 minutes she got me to sit up, then 5 minutes later again she told me to lie back down, another 5 minutes I was to sit up, another 5 minutes later I had to lie back down. This happened a few more times, all the while I felt totally fine though.
Eventually they let me go, I got made to drink a load of juice and eat a chocolate biscuit first though (they don't do tea any more, caffeine's bad for you apparently). I got back to the office and sat at my desk, ten minutes later it hit me. I felt like my head was full of cotton wool, I was dizzy and hot and just felt weird. I went home and spent the rest of the night flat on my back.

I've done it once but I shan't be doing it again!
