Matzoh, Wine, Marror, Lettuce, Potatoes, Eggs, Meat, Mass Quantities. These rapid and large changes to our diet wreck havoc with our digestive systems. My suggestion to myself and all others is to drink lots and lots of water, especially in the morning and preferably shortly after awakening. Drink several cups of water before breakfast, at least two cups. Four cups is better. Never drink cold water. I like to mix boiling water and either tap or spring water.
