Without getting into details, I actually cannot eat alot of food at once and need to take decent sized breaks between meals. I also need to somewhat eat smaller portions. I rarely eat dessert for this reason
This time of year especially the break isnt long enough between Lunch and Shalosh Seudos, so I dont usually eat Shalosh Seudos (Dont tell me its a Mitzvah, Its no Mitzvah to get violently ill which is what happens, I generally cannot eat another meal if I end at about 2, until about 6 or 7)
