Hi all fellow insomniacs. I am currently undergoing chemotherapy for muscle invasive bladder cancer prior to having my bladder removed.. I have two more sessions left to do. I find my sleep pattern very erratic usually unable to sleep for long periods as I can go to the bathroom four/five times a night and even more after chemo.. I’m hoping that once I have my bladder removed I may have what for is a dream at present six/seven hours sleep..
