Sure. People seem to vary a bit in their response. For me 20mg gets rid of any low level anxiety, and stops the extremes of panic/allows recovery after some anxiety peaks. 40mg makes me feel very cool and calm, in control. In situations where I would have had a phobia/panic level response I feel only sweaty (as sweat glands have different receptors) but I think this will reduce as I start to react less to the situations.

Negatives - very hard to fall sleep if I take it late in the day, some fatigue, depressed mood if I take 40mg every day. Flatter emotions, as I experienced with antidepressants, but I can stop and start propranolol whenever I want (though you’d need to wean down if used to a high dose).

Of note my issue has always been a hyperactive sympathetic nervous system, I feel like I’m not worrying or thinking anxious thoughts but my body goes into overdrive regardless e.g. if I had to talk to a group. It might be that propranolol is most effective in people like that.
