Hi @Nuala, I was diagnosed just before Christmas too and have had insomnia since. I sometimes can't get off to sleep and sometimes wake up about 4am and sometimes both. I have a 3 year old so she just started to sleep through and this happened. So I'm non-stop frazzled for years now! I have tried sleep podcasts (podbean has a load of them) and one called sleep well (she recommends the snack before bed to avoid low sugar in the night). I have also tried a breathing technique - breath in for 4, hold for 7 and breath out for 8 and have found that helps a lot. I am having the oncotype done so am waiting to find out if I need chemo. I have been reasonably ok this week since I had a meltdown on Sunday night just from frustration. Good luck with your treatment and hopefully you'll get some improved sleep soon.
