I've finished my one month. Mostly it was a very positive experience. I've learned how difficult it is to find fair trade chocolate options. I turned down a few delicious chocolately treats I was offered, but will make an effort to prepare my own using fair trade cocoa and chocolate.
I also realize that I had it relatively easy. I do not drink tea or coffee, and as much as I would like to, don't have a few cups of chocolate every day.
There are a number of other people who blogged about their experiences in the Fair Trade Challenge. They are definitely worth reading!
