I'm taking mine on Mon and my doc said it's fine to eat all day except the hour after I drink the glucose drink. I know some doctors make you fast the entire day though. I was thinking about just having some eggs with cheese in the morning and nothing for lunch (my appointment is at 12p, so I have to drink the drink at 11a). I just really want to pass and not have to do the 3 hour test. My mom had gestational diabetes with me and she said it was really hard to manage, but well worth it! 😊
