Argh!

My mom woke me up this morning to tell me I had a CT scan tomorrow and that we needed to pick up the contrast dye whatever. First off, holycrapWTH?! I was going to pack up my car and drive back to school early in the day so I could get everything in place before classes on Thursday. Well, that plan's out the window now since the test is at 12:30. Secondly, holycrapWTH?! I have to drink the dye whatever tonight. It's not a little amount. 450 mL, people. That's, well, I don't know how much in ounces, but it's about two soda can's worth. I'm trying to drink it now, but I'm having serious problems. Now, the stuff does kinda smell like muffins, which is both weird and amusing at the same time, but it tastes like CHALK! I may even have eaten chalk at one point that tastes better than this. I really don't know how I'm going to get it all down...
