I took it for about a year or year and a half. I did not have any terrible side effects other than a little fatigue/lethargy and there are sexual side effects for males (lower quality erections).
There is another medicine called Diovan which is a cousin to the ACE's (I couldn't take ACE's either--sore muscles, fatigue, etc.). I take Diovan and I have no problems of any kind. You might want to try that.
