Thanks, everyone, for the replies and information. I'm really doing quite well with the tincture of opium. I was even able to go on an overnight trip last week and not have to worry constantly about
where the nearest bathroom was. This works better for me than anything else I've tried, so I'm going to keep it up. My doctor assures me that I will not become addicted in any way, as the dosage is too small. I take just enough to keep the diarrhea at bay.
