@jj70 @Romla As I've adjusted to the BC diagnosis, I suspect that's not a factor like it was, other than every now and then when I go on a worry bender. I think chemotherapy has definitely been a contributer: drugs, bowel problems. It will be interesting to see what happens as I move out of this phase of treatment. However for me at the moment it's the hot flushes. Like bloody clockwork all night long. I can't recall when I last strung together more than 2 - 3 hours sleep. I feel like the walking dead most days :#
