I finally took pictures of the Honest Teas that I drank in spring semester of 2012, as well as the few I had on my visited down in the summer of 2012.
The results? Spring semester I drank 20, summer I drank 7. Fall of 2011 I drank 21, so there was a slight decline from fall to spring. (Keep in mind I don't teach in the summer and drive down less than once a week.) However, there is still not enough data to come to any conclusions. I must continue to drink my teas, keep them, and photograph them. I'm already building my fall collection.
