Hope you are doing well now and the test was effective giving results to the good side of what they see.
I have had 2 of those tests. They are interesting to the personal body sensations. I cannot say fun or not fun, nor either way on the comfort level, just interesting.
Pouring the contents into a bottle in a rather heavy lead lined container with similar top then removing the top wearing a 2.5 pound lead lined glove, filling a small cup and telling you to drink it.
WTF? I about freaked out the first time around. He said not to worry because he does it all the time and one or 2 or so is no problem.
I checked after both tests. No, no glow on 1 or 2 evacuation and and my wife confirmed I was not more visible at night.
