I feeling tired and drug out after having 4 (6 hr) Rutiximab infusions

I had 4 infusions of Rutixima and had no issues. After the infusions I’ve had two blood tests two weeks apart and the results were very good. On 8/4/25 after waiting a month I will get another blood test. If those results are good I will get tested monthly if my CLL goes south on me then my Doctor and I will have a discussion on the next course of treatment. She has mentioned pills (chemotherapy in pill form) but we will cross that bridge when it needs to be crossed. My infusions have made my life so much better, especially more energy. My only issue is waiting for blood tests etc. waiting is starting to wear on me. But I feel good, have a positive attitude and hope that things turn out good. I am 77 and have lived a very fulfilling life but I also realize that in the end we are all terminal. My advice have a positive attitude.

My infusion team wanted to do 6 hr. sessions. My doc said "No. Do 8 2 hr. sessions." No side effects.
He stopped after 4 sessions and said there is no hard proof that 8 is better than 4.
My bloods (cbc) are terrific now, with indicators that hairy cells are still taking up space. I have never felt better.
He is chair of Hemo/Onco.
(I was not always so fortunate with docs).
