I bought a box of thin mints last month.
I was able to “restrain” myself to eating about 8 a day; the box lasted for 4 or 5 days.
I enjoyed them and felt just fine afterwards, so I never thought, “I wish I hadn’t….”, but since I’m about 10 pounds overweight, I still feel that I shouldn’t have. My rationale for eating them is that I think the Girl Scouts is a good and inclusive organization, so that’s my symbiotic way of supporting them. ;-p
