Hey ladies! So i go for my glucose test in a couple weeks and im soo scared for some reason. I have really bad anxiety and knowing what exactly will happen often helps. Sooo what happens?! Lol like how much do u have to drink? What does it taste like? I think ill have to do the orange but if they have other flavours, whats the best? Things like that. Anything will help lol
