הChelek 5
- Do not eat anything after the Afikoman. If you did, eat the Afikoman once more so that the flavor of the mitzva will linger in your mouth. (ShA — MB )
- The poskim differ in regard to drinking after the Afikoman. Lechatchila, be careful not to drink anything but water. (MB )
- Do not fall asleep in the middle of eating the Afikoman. If you do, it will be considered as if you are in a different place when you wake up. (ShA — MB )
