I'm on an ACE called lisinopril. I have not had any side effects, and it has brought my BP down to a nice general range of 110/65. Previously it was in the 140/95 range.
I'm not sure if all ACE's have this side effect, but lisinopril in particular can cause a dry cough which apparently is highly annoying. Luckily, I haven't experienced this. Not sure if Enalapril has that same side effect.
