So I went for my 3 hour test today. After getting my second hour of blood drawn, I started to feel faint and told the lab tech to please watch me closely. She sat me back in the lobby and I immediately knew I was about to pass out. I rushed back into the lab and went to the floor. I don't know how long I passed out for but then I threw up everywhere. Super embarrassing!! And now I have to go back next week to retake the test. Anyone else experience that during the test?
