I too have light headedness,dizziness,cough & ED problems. have been on Lisinopril 3 Months. Hated the stuff. Finally got my Doctor to change. Trying Diovan now.Why can't someone do something about this drug? Doctors just won't believe anyone! After 1 week I do feel a lot better,never really realized just how bad I actually felt on it.We'll see how the Diovan works,but am I early of this one too.
