Hey
I feel your pain. I have tried just about most suggestions and still struggle on days - i have put that down to "path that must be walked".
I had a great sleep last night after pure exhaustion...maybe when you get to the exhaustion you too will sleep!
Ive been told about Melatonin too but im in aus so not sure if we have it here....
PS well done on 6 days
keep up the good work
