I started with fludarabine and rituximab which wasn't great. I had feelings of hot and cold, spots before my eyes, vertigo and blacking out. My haematologist was there in minutes, lowered my dose and I was able to complete the course over 6 hours without further adverse effects. Subsequent treatments (the next 4 months) were bendamustine and rituximab intravenous drips. No problems at all. The prognosis for bendamustine isn't as good as fludarabine - the likely effective period being 4 or 5 years as opposed to 15 years for fludarabine, but thats life.
Overall, the post treatment fatigue and brain fog was a surprise and not a good one. But I wasn't in pain. I often slept 10 to 15 hours a day with no energy whatsoever. But the worst part was getting covid while immune supressed. This just about killed me. Fever, brain fog and no appetite. I lost 35 kg.
But I'm through it. Out the other side and able to play with my grandchildren. Overall I'm grateful.
