I had to do the 3-hour test about a month ago. It was torturous! The stuff you have to drink (100 gram glucose solution) is twice as strong as the 1-hour (50 gram) screening. I nearly passed out during the first hour. I was extremely nauseous. By the time they took my last blood sample, I was shaking from the glycemic response! I went immediately to Applebees and had some protein! Then took the rest of the day off work because I felt lousy.
Hope you get good results today!
