Alternative to three hour glucose test?

I want to start by saying that if it really is the only option, I of course would do it. I just want to see if I can avoid it.

I got my 1 hour test done yesterday and they said my results were 10 points out of the range and that I need the other test. But the only problem is that I feel like my body had a really rough reaction to even just the one hour and I’m worried about how I will handle the three hour. I got my blood drawn for the one hour at 6 last night and for the rest of the night, had really bad anxiety. Then at night, I couldn’t sleep until I felt like my body just shut down and then I woke up 4 hours later and couldn’t go back to sleep again. I also have had an upset stomach out of both ends and almost passed out.
