Upper GI with a tight fill

[Guest guest]

My doctor wants me to have an upper GI because I haven't had one in a

couple years, and my band is now pretty tight again (following a

loosening during pregnancy, etc). Do they normally schedule these in

the morning (I assume you can't eat ahead of time). The reason I ask is

because it's tough for me to drink much in the morning. What if I can't

swallow the barium stuff? Any experiences?

Thanks,
