How have you tolerated Kisquli (ribociclib)?

My new breast oncologist has suggested Kisquli (ribociclib) to add on to my exemestane. A decision has to be made fast since I am 13 months out since my BM. I am now finding that the "medication" oncologists (at a couple of leading breast centers) are leaving it up to the patient to make the final decision to start any new medications or refuse. Facts are presented (as the physician sees them) to the patient, no guarantees made and the oncologist "seems" to be in the middle. I get it - the "informed decision" but it's a very tough call to make. How are those of you, taking Kisquli, finding the tolerance for the side effects (of which there are many, as we all know) of this drug?
Onco type 14, 1 + node, cancer in both breasts, stage IIb. The AI was the only recommended treatment made to me in 2025. Apparently "guidelines" have changed in 1 year.
