Hi thank you for your reply. I too have tried antihistamine based drugs and i have magnesium too. Basically I have tried everything and Zopiclone works for me as long as i only use it at weekends as my body gets used to it. My GP really is against giving me Zopiclone because of the addiction issues. I had it for about 3 months last year but was taken off it mores the pity. I went back to gp last week and was given a week or 2 weeks supply if i take half a dose. You are right tho the effects of lack of sleep has its own consequences. I cant believe you have had it for that long. I will speak to my oncology team at next appointment and see if they can help with a prescription.
