I am sort of still doing it. I don't follow it week by week. I downloaded all the menu plans from the archive and just pick from those ones. I think I have about 5 plans that I have repeated a number of times because they were easy and the recipes aren't "new" anymore. The toughest thing I found with the Fresh 20 was that every day was a new recipe and by the end of the day I just didn't have the mental power to figure out a new recipe every night.
I haven't done it all summer. We'd been doing it since last August and my H was tired of all the new recipes.
I really love the idea of it, but the food was really hit or miss for us. I kept doing it for as long as I did because it made it so easy for me to grocery shop. I definitely have some recipes that are keepers, but I'll likely cancel when this 3 month period is up.
