How long for benzo tolerance to go back to zero?

[Steady3]

I've been prescribed 30mg temazepam for the past month, and have probably taken one before bed 11 times or so. I've taken 60mg once. Have zero alcohol tolerance, mild opiate tolerance, and very little benzo tolerance. Any ideas of how long it will take of not taking any benzos in order to reduce what little tolerance I have back to nothing(or at least as little as possible? Is resetting to nothing even possible?)

Thanks
