Yesterday's bladder cancer BCG treatment was much milder than the first treatment. If you are going to have this treatment let me give you some advice. Only take sips of water, if you need them, after dinner the night before. BCG is an irritant. If you have to go, it will really pressure you to go and you may not be able to stop it. Having your system basically relatively empty (but healthy) made it so that I could make 2 hours fairly easily. I could have gone longer but I had a Zoom meeting and didn't want to have to deal with it. I was also very calm and stayed seated and still most of the time. That's important too, but I was so glad to be able to do it!
