I posted last week about failing the early 1 hour with a level of 184 and today was my 3 hour. My fasting level was 76, 1 hour was 201 (fail), 2 hour was 144, and 3 hour was 108! Since I only failed one out of four, it's considered passing and I don't need to do anything special except repeat the 3 hour around 24 weeks.
So.. If you fail the 1 hour horribly like I did, it doesn't automatically mean you'll fail the 3!
The drink isn't horrible but fasting during morning sickness is not ideal. I was craving a cracker or something to calm my nausea this AM. The nurses let me lay down between draws and so I powered through it.
