I think I've actually finally forced myself to form a new habit. I officially completed goal #55 - take a multivitamin every day - a few months ago, but Greg and I have been pretty good about continuing to do so.
The only times we really miss are those nights that we eat out, which isn't often. Other than that, the vitamin containers stay sitting out on our kitchen counter as a daily reminder while we're cleaning up after dinner. Go us!
