I've been off Lisinopril for 2 weeks now. The dizziness, light headedness, and general overall flu like feelings are pretty much gone. I still have a touch of the irregular heatbeat stuff but nothing like it was. The doc is running me through some additional cardiac tests (treadmill, etc.) just to be sure. For the most part, though, I feel like way gobs better. BP really doesn't seem to have changed much but I am on a beta blocker too which helps with BP. Doc isn't thrilled with the "no Lisinopril" order from me. She says it's the best drug for protecting kidneys in diabetics. But, we're going to see how it goes.
