How often must I…or how little?

” 39] In conclusion, since we have now the true understanding and doctrine of the Sacrament, there is indeed need of some admonition and exhortation, that men may not let so great a treasure which is daily administered and distributed among Christians pass by unheeded, that is, that those who would be Christians make ready to receive this venerable Sacrament often. 40] For we see that men seem weary and lazy with respect to it; and there is a great multitude of such as hear the Gospel, and, because the nonsense of the Pope has been abolished, and we are freed from his laws and coercion, go one, two, three years, or even longer without the Sacrament, as though they were such strong Christians that they have no need of it; 41] and some allow themselves to be prevented and deterred by the pretense that we have taught that no one should approach it except those who feel hunger and thirst, which urge them to it. Some pretend that it is a matter of liberty and not necessary, and that it is sufficient to believe without it; and thus for the most part they go so far that they become quite brutish, and finally despise both the Sacrament and the Word of God.”
