Side effects of ace inhibitors symptoms and conditions

Started Lisinopril eight weeks ago and took it for three weeks. I suffered the consistent cough. However the worst was the altered taste. It is worse than just metallic, it is bitter and food taste can change mid-meal. The problem started after the first week taking the medication and has not gone away even though I am five weeks since the last dose. I am concerned as to how long it takes this side effect to go away.
