I was diagnosed 10/06, had a TURB and began 6 weeks of BCG. Initially side effects were minimal, some discomfort peeing. Side effects increased towards the last treatment. I received my treatments in the AM, returned to work late morning, but then I had access to facilites. By the next day, effects had eased with less urgency. Everyone has a different reaction, mine was tolerable. I will tell you however, that in the two next series of 3 each, reaction was greatly increased and I would not suggest planning anything that day for sure, if you need further BCG treatments. Good luck, it's not so bad.
