I took it for 1 yr, starting at the dose in my comment above. Restless legs resolved in a few days, but active tremors, mostly in the hands, persisted, tho they less severe after starting propranolol. As with all drugs, there can be side effects, tho I had none; to the contrary, the beta blocker may have calmed my overactive sympathetic nervous system. Anyhow, I reduced the dose 3 or 4 times, once having to reup it due to a slight increase in tremors. I discontinued it after 1 yr of use, altho my dose was like 5 mg/day. It's very important to taper off, not stop taking inderal or propranolol abruptly.

I read about inderal/propranolol online, either the Mayo or CLE clinic website. It was at the start of covid and I couldn't get in to see a dr; I had to go to the local ER and ask for the drug by name.
