Not sleeping

I fortunately have a wonder and compassionate GP. I have multiple other medical conditions aside from this whole cancer gig. My sleep was horrendous in that the slightest noise would waken me...even a mouse walking down the road and letting off a fart would have me up. One of the conditions I have affects all my joints, and the constant turning to relieve pain would have the same effect. My doctor said that I had to have some good quality sleep and now has me on something for sleep every night. I have three different drugs which are rotated as my body adjusts to each, so that by the time I get back to number one, it is effective again. I told him that other doctors were very reluctant to prescribe nightly sleeping tablets as I would become "dependent" on them. He dismissed that and said "Well diabetics need their insulin daily and nobody accuses them of being addicted or drug dependent". I said that in my case, this was the least of his worries. Lovely man...
