Do as I say, take thy meat as it cometh, or provide it according to reason, and take it gladly, as a thing that thou needest; but be well aware of lusts that cometh with need, eschew too much as well as too little. And having done, if after it there arise in thee a remorse or biting of conscience, that thou hast eaten too much, and thereupon thou becomest sad and heavy with overmuch bitterness against thyself, lift up the desire of thy heart to thy good Lord Jesus, and acknowledge thyself a wretch, and a beast, and ask Him forgiveness, and say that thou wilt amend it, and pray that he will forgive thee. Leave off then, and think no further of it, nor strive so much with the vice, as if thou wouldst destroy it utterly, for it is not worth the doing so, neither shalt thou be ever able to bring it about that way; but set thyself about some other business bodily or ghostly, according as thou findest thyself best disposed, that thereby thou mayest profit more in other virtues, as in humility and charity. (John Climacus)

Leave off then and think no further of it... but set thyself about some other business.

There is a tendency among religious people to make more of our sins than the sins deserve. This is a form of pride.

This is especially the case with sins that have their origin in natural need. The temptation will recur.

We should recognize the sin and ask forgiveness, confident of God's grace.

Then -rather than obsess over the temptation - we ought give our attention to how we serve God and neighbor. There is a great need for our attention.
