The recent discussion on S-days had some really useful ideas for me. I have known for some time that I always do better when I tell myself TO DO something rather than NOT to do something. (For example, "eat more veggies and fruit" works better for me than "don't eat junk"... and works out about the same as the good stuff edges out the bad.) Just how my mind works...focusing on a positive goal is more productive than telling myself to avoid a negative.
So... what does "don't be an idiot" look like when it's turned around into a positive? The answer (for me) lay in the discussion on one of the other threads: Be mindful.
Note that there are still no restrictions on what I can have on an S-day. If I really want it, it's mine!

I tried this out this weekend, and absolutely LOVE it. My servings of snacks/sweets/seconds dropped, but my enjoyment of them rose.
This is exactly the middle-step I needed between No-S and Some S Sometimes. Thanks to everyone who contributed to that enlightening discussion!
