That's an interesting tip, LT - thanks. I almost blacked out once after a blood test and I was already phobic before that, but I've had to have a lot recently. I find it really helps a lot to lie down while it's happening (and then get up very slowly and gradually afterwards) - it means my blood pressure can't plummet so easily. I also have a drink of water and a biscuit or something immediately afterwards.
I'm really glad that helped the experience for you! Five vials is a lot...

Congrats on getting it over with! I always feel like they should give me a sticker or a lollipop or something afterwards...
