36. Is there an obligation to sit in the Sukkah on Shemini Atzeret in the diaspora?
According to most opinions, the Yom Tov meals must be eaten in the Sukkah. The blessing for the Sukkah is certainly not recited. One may have snacks and drinks in the house, since even on Sukkot there is no obligation to have them in the Sukkah. Some have the custom to be lenient on Shemini Atzeret and eat some or all of the Yom Tov meal in the house. A person should not be lenient unless he has a strong family custom regarding this.
Regarding sleeping, the widespread custom is to be lenient and permit sleeping in the house.
