I was diagnosed with Parkinson's 8 years ago, am still in first stage with unilateral symptoms which respond very well to dopamine replacement therapy. Within the past six months or so I have started to experience fecal urgency and on a couple of occasions was just lucky enough to locate a toilet in time. I do not suffer from diarrhoea and sometimes have bouts of constipation. When my meds begin to wear off and before the next dose kicks in I suffer from urinary frequency. My doctor prescribed lomotil, I used it once or twice when easy access to toilets was a problem and it seemed to work ok. I am going on a cruise holiday which may involve one or two bus journies for shore excursions and am a bit concerned. I am an active 60 year old female. Is there anything else I can do or should I just avoid bus journies. I am 5ft 2 inches in height and weigh 130 lbs. I also have osteopenia in the hips.
