There always has to be the one to dissent - sorry.

I had GD with DS and tomorrow am going in for a GTT for DD. I also did one at about 11 weeks this time round because of my previous ob history. My ob is a high risk ob and hasn't mentioned the high carb diet to me - I just need to fast from 12am (water is allowed) the night before. I'm just eating as normal prior which I've done the previous two times. My instructions have been the same with both obs I've had as well.

I also did the first GTT at Dorevitch - just walked in and made sure they knew I was doing the GTT so they will slot me in straight away. Usually you don't even need to take a number. Tomorrow I'm doing it at the Royal Women's labs (only cause I'm seeing my ob in the meantime) and no appointment necessary. However, it may be different in other states etc. I'd just turn up after having fasted.

Good-luck and I hope you are one of the many who fail the first and pass the second.
