Glucose Testing

I went to the doctor to take my glucose test and failed it because they didn't tell me abt not eating after 12 am . After that I had to go to someone else to do a 3hr Glucose test . The nurse told me that she has to take my blood four times when doing the 3hr test . I wasn't informed abt all the blood work . I started vomiting because I really have a hard time drinking whatever they have us drinking .
