Beta blockers are serious medications used for high blood pressure. They haave a variety of side effects including the exacerbation of asthma as the beta-adrenergic receptors (why they're called beta blockers) have a fairly high density in the lungs and asthmatics are particularly sensitive to the depression of their respiratory function.

This drug class has some depressant effects and like many depressants has deleterious effects on memory.

I would suggest avoiding drugs like this to calm your nerves due to their serious systemic side effects.

You're much better off with alcohol or, better yet, benzodiazapines like diazapam (Valium).

Better yet, just play poker until flopping a set or even flopping quads doesn't really change your mood that much.
