so I have a sugar test at my next appointment but they didn't tell if I could eat or not before I…

You can eat just nothin high in sugar

do you have the referral form

My doctor told me to eat whatever I wanted. I passed mine no problem.

I was told "you don't have to fast but don't go in right after eating a giant bowl of fruit loops"

I was told to fast. Eating food can cause you to fail; especially if you eat something very sugary.

Hope this helps
