CLL Treatment side effects

I am a 78 year old male living in Southern California. I was diagnosed with CLL in Jan 2022 and told to wait and watch. In October 2025 the waiting was over. I am being treated at Desert Hematology in Rancho Mirage with cycles of Chemo and Saline infusions. I completed Cycle 2 last week and the plan is to start Cycle 3 next week. My side effects are dizziness, brain fog, no energy, chills, night sweats and wheezing and coughing. Each day brings side effects and its starting to wear me down - I never feel good or like I can do anything? Sound familiar to anyone?
