I have done it a lot. It doesnt hurt other than a little poke. It takes 2 hours the first time, as they give you a mini phisical before, then it takes an hour or so.
The place i went had wireless internet, so i just sat there and watched tv on my laptop.
Very easy, although I could never bring myself to look while they poke me, i always looked away.
I always thought that them taking the needle out was worse than putting it in, putting it in is just a little prick, taking it out... kinda feels like what Neo did in the matrix, when he pulled the thing out of the back of his head while in the womb thing...
Not painfull, just.... weird.
Edit: Oh, and drink water, a lot of water, more than an hour before you go. It will go faster that way.
