urinary retention
"This helped my neurogenic bladder and neurogenic bowel condition.  After 2 years, tho, it started giving me nausea and vomiting.  I see you are supposed to take it 1 hr before or 2 hrs after a meal or it can cause nausea and vomiting.  I hadn't ever paid attention to that and I was fine, now I can't tolerate it and am sad bc it really helped both conditions."
