ribociclib... Feeling rubbish?

Hi, Just wondering if there are others on here taking ribociclib and struggling with the three weeks on symptoms? The bone sapping tiredness, upset stomach and lethargy are tough, but the one week a month off to feel normal is kind of great (apart from it reminding me of what near normality could be). Been 3 months since diagnosis now and I’m still not sure where my head is at, few people know what’s going on (which I still prefer) but a pop in to clinic for bloods today reminds me that there are so many people who “look normal” but are living with the same thing.
