Hi @rafcer
I have already had 3 BCG treatments and I did not find these painful in any way.

I dealt with keeping this installation in my bladder for 2 hours by neither eating nor drinking the night before. (If I had eaten, I would become extremely thirsty and wanted to avoid this) Although I was told you should not eat or drink 4 hours prior to having the BCG, I found prolonging this time worked better for me.

I was also instructed to turn every 15 minutes on each of the 4 sides, thereby giving the BCG an opportunity to coat each part of my bladder. As a diversionary tactic you may want to listen to some music or watch tv for those two hours. During each of the three times, fortunately I was able to maintain it.

On the issue of what to do when urinating for the next 6 hours, the instruction sheet I was given stated:
. Men/women should sit on the toilet seat to urinate.
. Immediately after urinating, add 2 cups of undiluted bleach to the toilet and closed the lid.
. Let bleach stand for 15 minutes before flushing to disinfect the toilet.
. Drink plenty of water to flush any remaining BCG bacteria out of your bladder.

Of course, each person reacts differently to this instillation and I was nervous. I think it is only natural to become apprehensive but once we become familiar with something, we find it was not warranted.

I wish you success with this BCG treatment.
