In February of last year I was diagnosed with an early case of prostate cancer. It took until November to get in order to have the radiated seeds implanted in the prostate to rid me of the disease. All is well now. In the meantime there were many exams which entailed shoving various objects into areas not used to having things rammed. Also, the gland was very much oversized than it would be naturally. To cut short the history what I am dealing with is that for the last few months, while the prostate has been healing, I sometimes have an urgent need to head for a commode, no pattern of urgency involved. I plan to go diving soon and I usually do the morning dive, from 8am to noon. I would like to not have a BM during these times. I would like to know if anyone would know if Imodium, taken at around 6am, would have a tendency to counteract this necessity. Or maybe there is another medication I could get that would do this.
