When I went off Topral I immediately started a different Beta Blocker, so I didn't have too many symptoms. Now, it's been a week since I've been off Corgard. I've had episodes of tachycardia and some higher pressures. I think it can take awhile to adjust to going off these pills. They must impact your nervous system also because I had horrid nightmares with Topral,among lots of other awful side effects. think you can still have residual side effects for several weeks as your body adjusts to the change. Hope you're feeling completely better soon.
