Not sure I understood what you connect to Evernote with Zapier to track vitamin D usage and mood (or was Zapier only relevant for the weather and the others are manual?). Also, if it's ok to ask- what's the ephemeral value in tracking these?
Vitamin D and mood was done manually for me. All of these were part of my Timeline notebook that focused on daily events.
I consider this "ephemeral" tracking because it's not data you can benefit from in a long term fashion. For example if my happiness ratio is up by 2 points if I take 5000 extra IU of vitamin D a day, it might not be true 10 years from now. Which makes any data you get useful for a short time, but then it's just noise. You can't leverage.
Since it's just data points you can't even claim there is an emotional connection to it. I do tend to be very light in terms of data though, perhaps you might like seeing things from 15 years ago.
