my recommendation, eat protein, preceeded by complex carbohydrates, go for a long walk to church or your spiritual practice, then come back the same way, or visit with members for a chat.
or walk or bike away from the hustle and bustle of city traffic and find paths that are out of the way. 'take' a picnic moment along the road to rest up, the walk or bike back.
after that you should feel like you are a new person altogether.
