Struggling to sleep

Hi my name is Tracey and I have multi myeloma, I’ve completed chemo and received an autologous stem cell transplant and have remained in remission however I really struggle to sleep well.  I have meds & oramorph but I really don’t want to take further meds.  Just wondering if anyone in the group has any tips they could offer.  I tend to struggle with pain when lying down at night but can’t find an answer to ease the pains.  I’d be grateful for any advice thanks for taking the time to read my post
