I went to see my PCP (on Tuesday, November 10th), and did a pulmonary function test, because I don't breathe deeply and sometimes my lips turn blue. The PF test showed that with a breathing treatment, I breathed easier. So he gave me a "puffer" (of albuterol) to use. He also Rx atenolol, for my tremors, and I took it for the first time today. So far, it has diminished my tremors but has not rid them completely, so the "jury is still out". However, if it can prevent another "episode" that would be a God send. I will let you all know.
