==Eating and Sleeping in the Sukkah==
===Outside Israel===# Outside Israel, on the eighth day of [[Sukkot]] (first day of Shemini Aseret), one should eat in the [[Sukkah]] without a Bracha of Leshev BaSukkah.<Ref>Rambam ([[Sukkah]] 6:13), Tur and
S”A 668:1 write that one should eat in the [[Sukkah]] on the eighth day of [[Sukkot]] but not make a Bracha. Kitzur Shulchan Aruch 138:4, Shu"t Yechave Daat 2:76 agree. This is based on the Gemara (Sukkah 47a) which presents a debate among the Amoraim regarding how residents of the Galut should conduct themselves in relation to Sukkah on Shemini Atzeret. The Gemara concludes that the proper practice is to sit in the Sukkah on Shemini Atzeret but omit the Beracha. The Gemara indicates that we do not take the Lulav on Shemini Atzeret. Tosafot 47a d"h maitav explain that reciting the Beracha would undermine the status of Shemini Atzeret by blatantly demonstrating that we are concerned perhaps the day is not truly Shemini Atzeret. <br />* Even though the pasuk in Parashat Emor (Leviticus 23:42) states בסוכות תשבו שבעת ימים, meaning you shall dwell in sukkot for seven days, we sit in the sukkah out of the doubt that it may be the 7th day of sukkot which would require sitting in a sukkah. </ref> There’s a minhag to be lenient regarding [[eating in the Sukkah]] on Shemini Aseret, however, one should not follow this unless one has accepted this practice from his parents or rabbis. <Ref> There’s an old minhag to be lenient not to eat in the [[Sukkah]] on Shemini Aseret from the time of Rashi recorded in Sefer HaPardes, Machzor Vitri (Siman 284), and Maharil (Hilchot [[lulav]]) (see nitei Gavriel (Arba Minim) Sh”t 4). The Piskei Teshuvot 668:1 brings in the name of the achronim that there’s room to be lenient since the Korban Netanel writes that the entire establishment of [[sitting in the Sukkah]] on the eighth day is based on the assumption that it’s comfortable and beloved to a person, however, if it’s cold or wind is present then one shouldn’t sit in the [[Sukkah]]. * see [http://hebrewbooks.org/14379 Meshiv Tzedek] by Rav Tzadok Hakohen of Lublin who wrote a complete pamphlet defending this practice of not sitting in the Sukkah.
* However, the Piskei Teshuvot concludes that one must be stringent based on the Sh”t Divrei Israel 1:200 that one shouldn't follow this minhag unless one has a tradition for it and it’s not comfortable outside.
* Aruch HaShulchan 668:3 writes that the gedolim have criticized those who just eat [[Kiddish]] in the [[Sukkah]] and then eat a meal inside. Mishna Brurah 668:5 also seems to hold that regarding eating one shouldn’t change from the ruling of S”A (which is based on an explicit gemara). Chacham Ovadia Yosef (Shu"t Yechave Daat 2:76 and Chazon Ovadyah ([[Sukkot]] pg 479)) also rules like Shulchan Aruc, as does Ben Ish Chai Vizot Haberacha: Halacha 13</ref>
# Regarding [[sleeping in the Sukkah]] on the eighth day of [[Sukkot]] (Shemini Aseret), there’s a dispute in the achronim. The Ashkenazim minhag is not to sleep in the [[Sukkah]], while Sephardim hold that one must sleep in the [[Sukkah]]. <Ref> Darkei Moshe 668:2 writes that there’s room to be lenient regarding sleeping outside the [[Sukkah]]. Kitzur Shulchan Aruch 138:5 writes that while the minhag is to be lenient about sleeping in the [[sukkah]], it's proper to be strict. Mishna Brurah 668:6 brings the opinion of the Gra who holds that one must sleep in the [[Sukkah]] on the eighth day but concludes that the minhag is to be lenient not to sleep in the [[Sukkah]]. However, the Bet Yosef 668 writes that sleeping is no different than [[eating in the Sukkah]]. Therefore, Chazon Ovadyah [[Sukkot]] (pg 479) and Ben Ish Chai Vizot Haberacha: Halacha 13 rule that Sephardim must sleep in the [[Sukkah]] like any other night of [[Sukkot]]. </ref>
===An American in Israel===
# A Jew from outside Israel who is visiting Israel for [[Sukkot]] should not eat in the [[Sukkah]] if it’s difficult to sit alone in the [[Sukkah]]. <Ref> Nitai Gavriel (Hilchot Arbah Minim Sh”t 8), Sh”t Minchat Yitzchak 9:54, [[Rabbi Shlomo Zalman Auerbach]] in Sh”t Minchat Shlomo 1:19, [[Rabbi Ovadyah Yosef]] in Chazon Ovadyah Sukkot (pg 480-1) and Shu"t Yechave Daat 2:76, Ot Hei LeOlam (vol 2 pg 87c; quoted by Sdei Chemed [[Sukkah]] 1)</ref> However, if he is alone anyway, such as if he’s in a hotel, Sephardim holds that he should eat in the [[Sukkah]], while Ashkenazim hold that in Israel one doesn't sit in the [[Sukkah]] on Shemini Aseret. <Ref> Chacham Ovadia Yosef (Chazon Ovadyah [[Sukkot]] (pg 480-1) and Shu"t Yechave Daat 2:76) writes explicitly that if it’s not difficult to eat in the [[Sukkah]] such as one is staying by himself then he should sit in the [[Sukkah]]. However, Sh”t Minchat Shlomo 1:19 exempts such a person in all circumstances. So writes the Piskei Teshuvot 668:2 in name of Sh”t Minchat Yitzchak and Sh”t Minchat Shlomo. </ref>
