I know people who SWEAR by this drug. But for me, Persoanlly, IT WAS HELL! I have been on Corgard (Nadalol) for 20 yrs. and it was just HARD to try to switch. It seems to be the drug of choice now days though for PVC's and also high BP..the high BP I don't have... I would wake up an dbe so scared, because with the Corgard, I can always take another "pinch" of it, nad with the Topral, I was on the XL and had to wait until morning. It just wasn't for me.
