At the hospital blood lab to do my 3hr glucose test AGAIN! My appointment was at 730 but the dr didn't sign the order so had to wait till 830 to start. They took my blood and said they would test it and if it's low enough I won't have to do the test but if not I'll have to drink that crap again, get my blood drawn every hour for 3 hours and it'll be a long morning. I'm so hungry right now ugh!
