sunnybear,
You will have to make that decision for yourself. Remember, the next 2 steps up are (ARB's and Calcium Channel Blockers) pricier and don't control as well.

I don't know how you stood 5 years of coughing...the thought of it makes me want to...well...COUGH!<hack-hack>

For me there was no choice- I just COULDN'T continue the Vasotec (enalapril.)
