Hi @Knorth26 and welcome to the forum,
I have a different blood cancer but I am aware that this is a topic that comes up a lot on the forum and there will be lots of members who will be able to share there experiences with you.
I have copied a couple of links below on previous chats. Members discuss what works for them and there are some useful links.
I hope you find value in the forum and that you are able to find some things that help with your fatigue. I know how hard it can be.
Take care and keep us updated on how you are doing
