oicud,

Welcome to NeuroTalk.

I have had similar events that were triggered by over-stimulation such as a loud environment. I have some rescue medicines that help. If my blood pressure is up with the anxiety, I take a propranolol. If it is just the anxiety, I take 1/2 dose of clonazepam. For me, one dose usually settles me down. Benzos like clonazepam should be taken sparingly.

If you want to try a natural treatment, 5-HTP might help. 100 mgs to start.

Stay away from all caffeine.
