I had the glucose challenge test yesterday. I didnt have to fast beforehand so I could have breakfast, but I wasnt meant to eat anything really sweet beforehand otherwise it could stuff up the test. I found the drink just tasted like very sweet lemonade and it looked like lemonade too and was fizzy. The first few sips were ok, but when I got to the end of the drink I was feeling a bit dodgy, but I didnt vomit or anything - i think it was 300ml in total. I got told to not do much at all for the next hour - no eating, no exercise - until after they had taken my blood.
I have a really lovely looking bruise too but its starting to fade.

The test wasnt really that bad. I just had to sit down for a while after drinking the stuff as I did feel a bit yuk but not enormously yuk.
