Recent diagnosis of early stage T1 NIMBC: Any tips?

Greetings. I am 69, and diagnosed in January with early stage T1 NIMBC. Was being treated for what was thought to be hematuria related kidney stones. Only risk factors were being male and over 55. Had 1 TURBT in Kansas City in January. Wanted a second opinion before going further. Got connected to Mayo Clinic at my wife’s suggestion. Have had 2 TURBT surgeries there since. Pathology has remained the same. T1 NMIBC. Scheduled to begin my 6 week BCG treatments in early June at Mayo. Encouraging, yet somewhat apprehensive. Have been doing a lot of reading up on the process, but would really appreciate any suggestions to make it go easier.
