What to eat before glucose test? Help I'm starving!!

Cici • Mama and Etsy shop owner! My etsy shop is SerenadeBaby
So it's 7:15 a.m, and I have the glucose test at 2:15 pm. The doctor I had at the moment told me to not eat anything sweet (what exactly that covers I'm not sure). But the problem is, every time I go there I get a different Doctor. Some people say not to eat at all and some say to eat how you regularly would. Help! It's the 1 hour glucose test. 😔
