Shacky,
Everyone is different. Mine was so long ago some details have left the brain. I know I had urgency, etc symptoms after each induction and want to say it was 4-6 weeks after my 2nd course of 6 were done for things to really settle down. With just maintenance perhaps that will also help. Also, you should know more what you look like inside with next scope. If still irritated maybe the doc would push your schedule out? Who knows? I am NOT encouraging to do what my treatment was but, it was 6 inductions, then 6 more and that was it. My URO who did intern under Dr. Lamm in San Antonio had many reasons for my protocol on my case. It was caught early. 2nd, every procedure no matter how minor involves some risk. 3rd, he saw I was vigilant on everything. What I am really saying there is no perfect answer of how much and how many treatments one takes. You basically have had 12 between the 2 agents. Reducing dosage strength is often done to 1/2, 13. 1/4 even 1/10. At the same time if it becomes too unbearable, nothing says you must continue....just make sure all appointments are kept especially scopes.
