I thought about it a lot when I was up for it, and I decided to have it because it would have been worse if I did have it and it was undiagnosed.
BUT it is your personal choice, if you don't want it then you don't have to have it...

Something to remember though is that it is completely random so even if your diet is great, you exercise etc you can still get it (I am not trying to scare you into it! LOL it;s just not like normal diabetes)
