I don't think my personality would do well with having a scheduled day to eat something.

I generally map out the week's meals when I go grocery shopping, but I don't set aside specific days for specific foods. Although we do tend to reserve weekends for eating out and weekdays for cooking at home. But even that is a fairly new phenomenon for me.

I had tacos for 4 days in a row this week. I would have kept going too, except I ran out of tacos.
