@mrollins, I hope you saw the helpful replies from @swh @judilafleur and @knottiebc. As always, everyone experiences side effects differently. As you can see from the replies, fatigue is something you will likely have to contend with and learn how to pace yourself when the fatigue hits.

While not bladder cancer specific, you might find this discussion helpful too:

As @swh says, she chose to have treatment on Friday to use the weekend to recover. Sue, did you find your energy returned throughout the week up to the next treatment?

@knottiebc, a diagnosis like cancer can be very loney, even if surrounded by people. It's tough to go through it alone. I'm glad that you found this forum to help connect with others living with bladder cancer. Pets like your Sheltie cannot be underestimated for the help and healing they bring:

Knottie, is your fatigue improving since the end of BCG treatment?
