Congrats on not eating the sandwich! I'm afraid if I smelled it I couldn't resist!
My NSV is along the same lines. Last night I had a SF Jello cup and was fine but I found my self miraculously standing in front of the freezer (I still don't remember how I got there!

) with my hand in the box of fudgesicles. They were on plan as sugar free but I didn't
need it.
I withdrew my hand and left it for my husband and went on about my business.
