Great news! I still have a 100%-zombielicious brain.
No tumors were found on the MRI. Since (from what I've been able to tell) MRIs don't detect siezure activity, unless one is in progress during the MRI, I can't rule them out. However, I am feeling more and more like the phantom smell was directly related to the virus I had. Even though the smell began two weeks prior to my illness...
Anyhow, I'm not going in for any other tests unless the phantom smells return. Let's hope they don't.
As for the upper GI, that also revealed nothing operable. The only thing it discovered was that my body processes food, liquid, etc., at a heavily increased rate of speed. We're talking Star Trek warp drive here. Zoooooom! The entire test was supposed to take up to 3 hours. It took me 30 minutes. I drank the barium, they quickly did an xray, and I had to drink more barium because it was already through the system. Rapido. What does that mean? Bollocks if I know. I'm guessing it partially explains the magnificent gut pains I get every day, though. Somehow.
New body, preferably the android species, please...
