Hi Iggy,
Welcome. You may not be "addicted" to Zopiclone, rather "dependent" on it. When you stop taking it (and are up until 3am - and restless), do you give in and just end up taking the pill to get you to sleep?
I used to use Zopiclone to sleep, and eventually had to take two for it to work. I wasn't addicted to it, however I was dependent. I didn't need it cause of the way it made me feel, nor did I crave the drug. If I didn't take it, I'd be awake until I gave in (literally 48+ hours awake). On the contrary, I did manage to wean myself off it over the course of a couple weeks. I'd take one and a half for a week, then cut down to only one for a week, then half for a week. When I got close to the end, I'd set my alarm to wake up at 5am (rather than 7am) just to make sure I was a little more tired at night. I also did yoga to help me calm down more at the end of my day.
I'd suggest talking to your doctor about the fact that you "require" a sleeping aid at night. I needed one for many years until I found another way to get to sleep. I wasn't a good sleeper my whole life, and had a very hard time falling/staying asleep. Perhaps, your doctor can give you some suggestions other than the obvious (exercise, eat healthy, take a warm bath at night, drink warm milk etc.).
Good luck, I hope to read about your solution soon
Sincerely,
