When will treatment stop?

Waldenstroms about 2 years
Now. On Ruxience and Octigam infusions and Brukinsa pills… also dexamethosone.. still anemic. Numbness in feet
Much better.
But Igm coming down and igg going up. Other than nausea and diarrhea and tiredness I think I’m doing much better.
Not losing weight consistently either anymore. At what point do infusions and meds stop?
