My prescription was denied (insurance screwup), 3 mg. of eszopiclone nightly for 4 years. I had also become a daily drinker. Drank to get through the withdrawals, they put me back on it, ended up in rehab. One of the best things that ever happened to me, as it got me sober.
YMMV. The valium should help a lot, a valium taper is how I got off everything.
