@Sister and @kmakm, I used the melatonin last year after chemo to reset and I think it really helped. I've decided to go back on it as the hot flushes and night sweats are back with avengence and really disturbing my sleep and I'm back to a zombie. It's non addictive and can be taken over long periods. My oncologist prescribed it the 2 mg ones and they are about $40 for 30 tablets. They don't affect your alertness in the mornings like benzodiazepines (temazepam) can. it will take a few days to build up in my system but hoping it works again and I can get back to the 7 hours sleep again with minimal waking.
Lucky for me both my GP and onc are all over insomnia and how lack of sleep affects you.
