My lunchtime ice cream experiment has backfired

Earlier this week, I asked the question, "Is it better to eat ice cream after lunch or dinner?" Many people answered, "yes!" I'm an ice cream lover too! I had been eating ice cream after dinner, but this week I wanted to try something a bit different. I was going to eat ice cream after lunch. My little clinical study backfired when I couldn't control myself from eating ice cream after dinner every night! So, I've decided that I should limit my ice cream consumption to once/day (otherwise, my BMI will go through the roof). However, now that I've gotten used to eating ice cream after lunch, I'm having a difficult time breaking that habit.
