fasting for the glucose test is pure torture for me because I'm awake the entire 8 hours every time 😫😖 (this is my 3rd time but only 2nd time testing) after the 3 hr testing is up I have to go straight to the Dr. for my Rhogam shot. I'm about to be so weak. I can't wait til today is over. All I can think about is food. 😢
