My doctor had to change my dosage to take at night versus taking it in the morning. Talk to your doctor and see if that helps.
I'm on Medicare (Kaiser) and even messaging my primary doctor is an ordeal.
Two days later (if I'm lucky) I get a response from a different doctor..."covering" for my primary doctor and wait another two days plus for another response offering to change the medication.
Since it's dangerous by itself to cut Amlodipine cold turkey...you have to wean yourself off of it, I'm skeptical of switching beta blockers.
Luckily I can sleep for several hours a couple of times during the day/evening, but I seem to be reliving my life...people and events I haven't thought of for over 50 years are suddenly a nightly experience.
It's not fun whatsoever. The other day, I woke up feeling like I had to rush to get dressed to go to my office...and took a minute to realize I've been retired for almost fifteen years.
