I've gotta take one on thursday, although its a 3 hour test. She said nothing to eat after midnight, come in at 8 am, they'd give me a drink and test my blood at 1 hour, 2 hours, and 3 hours. I am a little nervous about it...but I know a lot of people don't pass the 1 hour and do fine with the 3 hour so I'm holding out hope there. I have a lot of diabetes in my family so I'm just hoping I don't end up with GD...although there are a lot worse things I could end up with. Good luck with your test!
