It's very annoying, but most nights I can sleep.
I've been put on Atenolol, then Toprol XL
then acebutolol, and
none solved the problem. In fact, some made it worse. Some people just do not respond to such beta-blockers.
Sometimes Magnesium, Potassium, Calcium helps. I've had times when even SALT helped!! This leads us to consider STRESS factor as a possibility (thus independent of medication), and general mental factors (attitude, etc.).
