Banana Baraium

I am having a CT/PET test today. The oncologist wants to see where all the cancer is. I picked up the barium at the pharmacy and it was artificcally flavored with banana. The worst flavor ever. The stuff is thick and the taste is awful. Two full bottles..one that I drank last night, and one today for a 330pm appointment. I gag as I drink the horriable stuff and wonder what the point is. If they are no longer treating, why take the test? Christmas is next week....I wish I was baking today instead of going to the HMO to take this test. I may neve eat a banana again........
