The terms proximal (from Latin proximus, meaning 'nearest') and distal (from Latin distare, meaning 'to stand away from') are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively.
But, with Citrucel and/or Metamucil you can start with one teaspoon mixed in water or juice. If you have diarrhea don't use the preparation with artificial sweeteners. Use the one with sugar. I think artificial sweeteners (some of them) might cause more diarrhea.
Cipro or another antibiotic is recommended if the diarrhea is frequent or accompanied by cramps or nausea. Take one Cipro pill every 12 hours. If the diarrhea continues, repeat the Cipro. You may repeat Cipro every 12 hours until the symptoms subside.
