So far so good. I took 15mg and it gave me 6 hours of sleep. Doctor said "double up", I did and now I have ~9 hours of sleep which is what I want.

Dependency is not an issue for me - I had been on Klonopin for year and then easily came off within a week without any symptoms. I just do not get addicted to substances.

Tolerance is a big concern - that same Klonopin did nothing for me in terms of sleep - it was like a pop of Aspirin. I am afraid to get to that state with this drug. So it is good to know that there are others out there. In the meantime, I will enjoy my temporary solution.
