Over the last couple of weeks, I extended a little bit of what I was working on (ordering temporal annotations with regard to other treatments). Although initially I used tuples (time, description) to track changes in medication/smoking, I recently switched to using a custom object approach (i.e., a medication object, smoking history object, etc) and then sorting them according to time (which can be extracted simply via function).
This upcoming week is Simmons' spring break, so I'm hoping to spend some extra time working on not only finding temporal relationships between medications/smoking, etc, but also on visualizations of these in a more concrete timeline fashion, so we don't have to make timelines manually.
