Ray, your post was moved to this classification since this is where most of the "BCG EXPERTS" post!
Sounds as if you are well on your way. The thing about BCG is that the first few treatments usually go just as yours did. As your bladder, and your body, start to react to it (and this is what you WANT to happen) the reaction can get a little stronger. Fatigue is the most common factor. With me it usually came a day or two after each treatment and lasted about that long. Irritation, blood in the urine, some cramping.
As your treatments progress, if the side effects seem to become more than you can be comfortable with, it is possible for your urologist to reduce the dose significantly without losing any of the effectiveness of it. By the time I finished my maintenance rounds I was down to 1/3 the starting dose. Been two years now with no recurrence!!
Good luck to you.
