Hello there @Hellodolly, I’m sorry to read about these explosive episodes your other half has been having, if I understand correctly. Sounds horrible for you both.
While I don’t have experience of azacitidine, I do live with a related blood cancer to Chronic myelomonocytic leukaemia ('CMML') and know there’s a really great thread full of people with lived experiences of it. If you’d like to have a read and maybe reach out to others there, here’s a link: Recent diagnosis CMML
May I suggest giving the lovely Blood Cancer UK nurses a call to talk about the medical side of the medicine, we forum members can’t really offer medical advice. Their free number is 0808 2080 888.
Hope that helps a little @Hellodolly, hopefully other forum members can offer some more specific advice.
