Glucose screening test day

Today after work I went to the lab to have my glucose screening test. I had to drink this super sugary orange drink and sit there for an hour. After the hour was up I gave a blood sample and then next week my doc will let me know if I am needing a second test for gestational diabetes. So I sat there in the office experiencing the sugar high from the 50g of glucose and then the subsequent crash and oh was it painful! I sat there and then I got this raging headache from the crash. Not a fun time at all!!! I came home from this test feeling super drained and praying that I don't have to go through this one again for a very very long time.
