I was actually suprised with this episode. For most part, I'm more interested in the episodes that involve germs rather episodes who take a different concept. Still, this episode is satisfying.
The main idea of this episode is overdosing on medicines. I'm not sure if it's one of the better concepts, but it was executed very well. I'm pleased with Histamine's design. I feared she would look very similier to Drixine from "An Out Of Body Experience", but her unique-yet-similier design worked perfectly. Aside from that, the plot was good. Although there wasn't really a "climaxing" point, the whole episode progressed very well. I also think the beginning, the first part when Hector got a runny nose was very well-done and clever.
Shining Moment: The fight at the beginning.
