I will not harm myself with food today. I will stick to my plan and deal with tomorrow when tomorrow arrives.
I have a meal out this evening with a friend. I am going to a sushi restaurant. I have been there many times, as I love sushi. However, rice is NOT part of the plan. Tempura (i.e. bento box) is NOT part of the plan. I am going to order sashimi (just the fish, no rice) and a nice steaming bowl of miso soup. It will come with a salad. I could stretch to some gyoza if I really want to push the boat out; I have actually forgotten to eat my lunch which is unheard of.
So. Deep breaths, stick to the plan.
