Thank you everybody for your thoughts. It's given me a lot to think over and it might be worth trying maybe a few days out of a month- maybe as part of Survival Week.
I'm feeling pretty good as of right now- not tempted to pig out on anything (yet.) I'm still planning on going plant-less on thursday after the ratatouille is gone, just to see how it goes. Definitely can't do it long term. Plants are tasty!
