If I were you, and IMO, I'd get rid of all Benzos from your house so you don't continue with "rescue doses." All rescue doses do is prolong your healing and recovery. If they're not in your house, you can't reach for them in a moment of weakness. Yes, not sleeping sucks big time, but you can survive for a long time on very little sleep. You can function very well on little or no sleep too. I found that out during the 9-10 months of severe insomnia I had along with a host of other symptoms.
Sleep slowly returns and symptoms slowly fade. You can do this. It seems impossible at first, but you learn fantastic coping skills that help you to cross the finish line.
