Hey JW.,
Did you blackout while they were doing the blood draw, or just after?
I always have to lay down because I fainted once...out cold!
It alarmed the phlebotomist, so now I always just ask to be taken to a room with a cot. No sitting in the chairs for me anymore!
This is not unusual...especially if it is a fasting test. Low blood sugar always makes me whoozy.
I hope that you are feeling better now! Lots of H2O, good nutrition and rest for awhile.:)
S.C.
