Just to be clear, what dose are your tablets?
If I understand correctly, you have been taking Zopiclone for just three weeks. It also has fairly short half-life (this helps mitigate against dependency, but this is somewhat overcome by taking several doses per day.
Dependency depends upon several factors. Firstly, individual genetic makeup. Then there is length and frequency of use. The really good news here is that after thee weeks of use, you are unlikely to have developed dependency, or at least not a deep dependency.
What I would caution you against is drawing our your taper for any longer than is necessary. You see, even if you are tapering your dose, you are extending length of use, so you risk deepening your dependency while you are actually tapering. What does your doctor advise? It might be just stop taking them, or taper off over no more than a few weeks. If so, in general terms, I'd find it hard to argue against that after short-term use.
