I went in for my glucose test yesterday and my nurse called this morning to tell me I failed the darn thing. I've scheduled my three hour test for next week but I was wondering what goes on at the three hour test? All I was told was to not eat after midnight before the test. Will I have to drink another bottle of flat soda? Do I get an IV? What goes on at these tests? I've read from old threads to bring a book so I will definitely be doing that. Did any of you feel sick during/after the test?
