My DH used to depend on propranolol, for anxiety. Anxiety can manifest in different ways. He used to throw things at walls or the floor when in a rage. It was very intimidating, even though I knew then (and now) he wouldn’t harm a fly (too much pride). No, he never did it anywhere other than his home which he considered his place to stop masking and keeping it all in during the day.
I told him it had to stop. He said he didn’t know how. I suggested a counsellor. He saw one, for many months. CBT and a LOT of personal work. A lot. It wasn’t easy.
He now no longer needs propranolol, and he no longer gets angry, because he has learned how to control his anxiety. It’s been years now since his last episode, and I couldn’t even tell you exactly how many.
So, yes and no. It took a lot of work, and a deep desire to change.
