I never tried it, but looked at them back in the day as well and in my 5+ years of experience, I couldn't find anything short of another Rx drug to induce sleep and even those only worked for a night or 2 for me at the most. It was very difficult to do, but I let sleep come back on its own, without taking anything.
Nothing else works for Benzo-induced insomnia because the reason why you are not sleeping has nothing to do with sleep hygiene, melatonin production, etc.
Good luck!
