Avoid food that contains glue.

Add some bricks and nails to your diet. Once they enter your digestive tract
they will help to grind up all the hard matter for easier elimination. If
that doesn't work, try some sulfuric acid for quick action, but use it
moderately and don't ingest more than a quart or so at one time. You'll
notice a difference.
