I totally understand.
I found hospitalization helpful for immediate crisis, and out patient more helpful for long term. I don't know if that's helps any. Ativan should be fast acting as far as I know. Not really needing time to work. Sounds like maybe the Ativan is not enough at the moment.
I really feel for you. I'm glad your husband is being concerned and proactive here. Maybe your pdoc will have some idea what might be the better choice.
