Translation:Shulchan Aruch/Orach Chaim/299
299: To Neither Eat, Nor Perform Any Work, Before One will Recite Havdalah. Contains 10 seifim.
1 It is forbidden to eat anything, or even to drink wine or other drinks besides water, from when it will get dark until one will recite Havdalah. However, if one was sitting and eating while it is still day and it got dark upon him, he does not need to stop [even from drinking. Beis Yosef]. And if one was sitting and drinking and it got dark upon him, he needs to stop. And there are those who say, that these words apply in a situation when it is doubtful whether it's dark. But in a situation when it is certainly dark, even if one was sitting and eating, he spreads out a cloth and recites Havdalah and finishes his meal. Gloss: And the custom is spread like the first opinion.

They were drinking, and said 'come and let us recite havdalah' – if they wanted to drink again before havdalah, they need not recite a blessing again. And there is one who disagrees on the matter.
3
When one makes an interruption in order to recite havdalah, he does not need to recite the blessing "...Who Creates the fruit of the vine" over the havdalah cup. And there are those who say that he needs to.
4 When one was eating and it darkened, that we said that he does not need to stop, he finishes his meal and recites Grace After the Meal over the cup and afterwards recites havdalah over it. And if he has two cups, he says recites Grace After the Meal over one and havdalah over another.
5 One erred and ate before he recited havdalah – he could recite havdalah afterwards.
6 One forgot and did not recite havdalah at the conclusion of Shabbat – he recites havdalah until the end of Tuesday. And there are those who say that he does not recite havdalah except for all day Sunday and no further. And specifically "...Who Creates the fruit of the vine", and "...Distinguishes between sacred and mundane". However, over a candle and spices he does not recite a blessing except at the conclusion of Shabbat. And there is one who says that this that we maintain "one partook – he recites havdalah" – these words apply where he recited havdalah at the night of the conclusion of Shabbat. However, if one did not recite havdalah at night, since he partook, he no longer recites havdalah.
Gloss: And the main law is like the first opinion. And one who fasts 3 days and 3 nights should hear havdalah from others. And if there are no others near him, he could recite havdalah on Shabbat while it's still daytime and drink and afterwards accept the fast upon him. [Terumat HaDeshen, Siman 159]. See Siman 553.

One who recites havdalah over wine at his table, even if he recited havdalah before he washed his hands, exempts the wine that's in the meal, that he needs not recite a blessing over it. And there are those who say that it is not exempt unless he washed his hands before he recited havdalah.
Gloss: And if one recited havdalah first, one needs to afterwards recite the blessing embodying three. [Tosefos and Mordechai, Chapter "How Does One Recite Blessings"].
8 When one exempts wine that's in the meal, that he does not need to recite a blessing over it, he also does not need to recite an "after-blessing" over the havdalah cup. And if he has only one cup and he thinks that they will bring him more wine and he recited havdalah over that cup, and afterwards they did not bring him more, and he recited grace after the meal without a cup, there is one who says that he needs to recite an "after-blessing" over the havdalah cup.
9 If one desires to partake of a meal immediately after havdalah, he needs to be careful that he should not bring bread to the table before havdalah. And if he brought, he spreads a cloth over it and covers it because it is earlier in the verse, and he needs to give it priority if he will not cover it.
10 It is forbidden to do any work before one will recite havdalah. And if he recited havdalah in the prayer, it is permitted even though he has not yet recited havdalah over the cup. And if one needs to do work before he recited havdalah in the prayer, he says "Who Distinguishes between [the sacred and the mundane]" without a blessing and does work. Gloss: And likewise, women who do not recite Havdalah in the prayer, should be instructed that they should recite "Who Distinguishes between sacred and mundane" before they will perform a labor. [Kol Bo]. And there are those who say that all this is regarding an absolute labor such as writing and weaving. But igniting the lamp merely, or carrying out from domain to domain, does not need this [Rabbi Yerucham, Netiv 12, Part 19]. And from this, the custom spread to be lenient to light lamps immediately after the congregation said "Barchu", but the essence is like the first opinion. And there are those who say to draw water at the conclusion of every Sabbath, because the well of Miriam passes through all the wells at the conclusion of every Sabbath, and one who meets it and will drink from it will be healed from all his afflictions [Kol Bo]. And I did not see this custom. And see above, Siman 263, one who adds from the mundane to the holy, whether it is permitted to say to someone else who has recited havdalah, to do work for him.
