Glucose test help!

Desiree
I have my glucose test in about six and a half hours and I'm irrationally nervous about it. I have a thing with tastes! Also have a strong phobia of puking. My doctor told me that I can eat 28 Jellybeans instead, but those Jellybeans are the thick kind that my grandma used to have in a candy dish on her counter and they're SO gross. I almost don't know which would be worse-the drink or the Jellybeans. Give me it straight. Tell me your experiences! I also have to have the RH shot during the same visit 😩 I'm a big baby and I'll have to get over it, I know. Wish I could at least chase it with water😩😩😩
