I have had flu like symptoms for about three weeks steady now. I have been on lisinopril for about 5 - 6 months. I have no energy and after reading some of the comments, I am definitely going to ask for a different bp medication. I had knee surgery about 3 months ago, and I thought my fatigue was due to that. I think the medication has gradually built up in my system. It ran a bell when someone else said, they felt they were run over by a mack truck.
