There was a poem years ago that I used to see on coffee mugs they sold at Spencer Gifts:
Here I sit
I tried to shit,
but only farted
Well, I have some ways to resolve this!
First, only eat the requisite amount of matzah. You can have tuna salad and egg salad on lettuce instead of matzah, it's much less calories and the lettuce contains fiber which will help move the matzah out of your system.
Second, eat lots of fruits and vegetables. They are high in fiber as well as other nutrients. This will help move the matzah out of your system.
Finally, enjoy the rest of Pesach with less of a stomachache. Yeah!
