Failed 1 hour GTT

Of course the one test I was least worried about I failed last week with a 172. I went in today for my 3 hr and completely threw up the glucose drink within 10 mins of drinking it. I asked my DR for an alternative because there was no way I was drinking it again. We opted for the finger pricks test for 2 weeks 4 x a day instead. Has anyone done this method instead and passed?
