I got de-blooded today three times by two different doctors. I had to fast beforehand so the first time the lady filled about 7 vials of blood in the space of 5 minutes and I started fainting. Then all of a sudden she stopped so I stayed conscious, but my eyes were still blacking out so I couldn't see anything at all. She had to lead me to the bed thingy to lie down until my vision returned, lmao..
The second and third times were fine because she then made me drink some glucose syrup crap and then only three vials were taken each time with an hour's interval in between. I'm not squeamish about blood or needles but I've never been close to properly fainting before so it was a really strange experience.
I've eaten now but I still feel like I'm missing something. Blood, perhaps.
