No sugar! That's brave! Good idea tho. I have since fell off the wagon over a daily dose of gummy candies but I did go sugar free-ish (sugary treats not militant diet style) besides one cup of fruit juice per day and I saw a big difference in my skin and felt better. I have been meaning to get back.

As far as other addiction we don't think about, you are right with coffee being a big one. So many consume much more than the recommended 1 to 2 cups per day but many drink it like it's water. Sodas in North-America is the same. Having a few vices is ok but it does pile up one after another if not paying attention to our habits.

You should try coconut chips if you haven't yet.
