I have taken Lomotil for years, but it's at the point where it's needed daily, so I asked questions here, and now I take Imodium (or Rx Loperamide) on normal days, but for the bigger events, I go back to the Lomotil.Lomotil has worked for me by taking it one to two hours before I leave the house, and if needed I repeat the dose four or more hours later.I have also added Caltrate, which has helped stop the awful urgency.
