Not sure if this helps or applies to you Nuala, or anyone else. But I found while having chemo treatment, I couldn't sleep and was super (I mean really super) hungry all the time and the only thing I felt satisfied with was basically junk food, which I rarely ate prior to diagnoses. When I mentioned this to my chemo nurse and oncologist they both said it was probably the steroids given prior to chemo. Thus I had my steroids reduced to half, and then the following week reduced again. Wow, this certainly made a huge difference for me for both sleep and hunger.
