After faint

By 09:00am my pressure is back to something normal (around 120/80 - very good) but I still feel light-headed. May be due to being anemic (a condition that not eating much could have aggravated). 

Went in for immune system tests today but the results won't be back until Tuesday. They will also do a creatinine test, which is the basic measure of kidney function (creatinine is a by-product of the muscle function and it's level in the blood is maintained by the kidneys).
