I'm sorry the Librium is not enough.
I am guessing you have discussed your anxiety levels with your pdoc?
You must have a very high tolerance for clonazepam?
Unless I'm hypomanic, I'd be out cold if taking 2 mg. clonazepam.
I've realized that the manner in which I handle each decision on matters between me and hubby definitely affects the quality of our relationship together, as well as my relationship with myself. Mutual honesty and respect go a long way.
Only you know how much you'd needed the clonazepam. No judgment here.
In my opinion, I'd suggest you share this with your hubby. Yet, I don't pretend to have all of the facts in your case.

I don't know what his state of being "furious" entails. Give it all some thought.
