Hi there, my hubbie has cardiac amyloidosis, closely linked to myeloma, and is currently on a 4-6 month cycle of chemo (he also has fluid around the lungs which seems impossible to sort out, but that’s for another forum!). He’s really really struggling with sleep, does anyone else have this problem ...... and does anyone have any advice please? He’s so tired, yet can’t sleep, so frustrating. Thanks.
