Reply To: Tips For Fasting on Yom Kippur

There is a machlokes concerning whether one is allowed to take something to alleviate the fast the day before. While the Tzitz Eliezer allows one to take such a pill on Erev Yom Kippur, there is a view of the Chiddushei Chasam Sofer to R”H 9a and R’Zev Boskowitz of the Seder Mishna on the Rambam who say that there is a mitzvah of tosefes Yom Kippur requiring one to begin fasting early enough on Erev Yom Kippur to ensure that he will experience at least some small degree of hunger at the onset of Yom Kippur so by sunset you’re already hungry. The halacha le ma’aseh does seem to be the meikil view of the Tzitz Eliezer, who holds like Rav Zevin.
