Does anybody have any experience of this medication. I have suffered from chronic insomnia for the last 18 months and in absolute desperation started taking zopiclone about 8 months ago. After about 6 months it no longer worked and my GP prescribed Halcion, which I only took for a week due to a severe headache. Now I am finding I need 2 tablets to get to sleep. i have tried absolutely everything else eg, relaxation etc. I am so worried about the dependence I have developed on this drug and am very concerned that soon 2 tablets won't work either. Any advice would be welcome. Thanks heaps
