Vomited During 3hr glucose test-TWICE!

So for those of you who have done the three hour glucose test-I want to know your secret! I vomited 45mins after drinking the solution the first time. The second time I vomited 20mins drinking the solution. I am waiting to hear back from my doctor to see next steps. I don’t see any point in trying for the third time. Has this happened to anyone? And what were your alternative option??
