I take generic Propanolol, 40 mg. twice daily, to help prevent migraines, it has cut down my rate of migraines enough to make a difference. I'd forgotten about the fact that it is also used for anxiety. Now that I think back, I've been calmer since I began taking it also.

I found this on The Anxiety Community

How does it work? Propranolol blocks chemicals, such as adrenaline, and prevents them from increasing heart rate, blood pressure, and oxygen use. It effectively reduces autonomic nervous system arousal (e.g. performance anxiety symptoms, palpitations, hyperventilation, sweating, pounding heartbeat, nausea, disabling tremor). Full benefits in a few hours to weeks, depending on severity of disorder.

When I first started taking it, I had to deal with increased dizziness and fatigue, no longer have increased dizziness, and fatigue is back to my usual level.
