Glucose Test

Went to do my glucose test and didn't read the time its a 2 hour test not a 1 hour uuugghhh thought I had time while my daughter is in school but no not at all I have to get her in an hour so I have to go back after. i havent eaten supposed to be fasting for this test ugggghh lol I don't know if I will survive not eating all this time and go another 2 hours after. I meant to ask the lady can i drink water I can't remember. Anybody took 2 hour test that had to fast could u have water at least?

Update: Finally done the drink wasnt as bad as they use to be, had the lemon lime flavor. i only got a Lil nauseous towards my last hour. thank goodness I have food in my system now, I need a nap that was exhausting sitting there for 2 hours. Thanks ladies I'm catching up on my water intake I missed out on and some sleep.
