i had 2 minutes to drink it and then wait an hour in dr lobby wth out eating or drinking then had my blood drawn still waiting on results the only way i made it thru the bad taste was to joke with how yummy it tasted lol
i had to drink that stuff too lucky mine was orange flavored still tasted gross tho
3 hours is normally after failing the 1 hour. but I have to take the 3 hour soon and I don't think I'm gonna do it I don't drink pop now that I'm pregnant it makes me feel sick.
