chocolate to the rescue!

on my second trip to a store for my dad tonight @ 9:30 p.m; I had to purchase Lindts - Lindor Chocolates. I kept myself at eating only 2 on the drive home even though there are 12 in the package.
HOW??? Did I do that? especially after standing & staring at stool softeners for 10 minutes trying to decide which ones he needed.
