Q. Would it be better for someone needing to take questionable pills on Pesach, or any other time if they could be non kosher, to wait and take them after a heavy meal when one is completely satiated. At that state it would be considered an Achila Gassah or gluttonous eating and therefore permitted?
A. In principle, indeed Achila Gassah or gluttonous overeating is not considered usually a natural act of eating.
However, Poskim stress that it applies when one actually feels revulsion and repugnance to eating anymore. (Yumah 80b. See also Tosafos Pesachim 107b ,’Dilma”).
