Eating after the Grace After Meals

I ate bread and cheese 50 minutes ago and recited the Grace After Meals. I am still satiated from the meal, but I feel like having a toast. Am I obligated to recite the Grace After Meals again?

One must recite the Grace After Meals again. The question whether one is still satiated from the previous meal belongs to a different matter: if one forgot to recite the Grace after Meals, as long as one is still satiated from the meal, it is possible to recite the Grace and not lose the opportunity to recite this blessing.
