Assuming Lisinopril is an "ace inhibitor", I strongly recommend it. I have been taking Accupril for about 15 years....I've had Type 1 diabetes for 36 years. My doctor prescribed it years ago because all indications are that these ace inhibitors are extremely effective in preserving your kidneys. I once asked my endocrinologist, who's practiced endocrinology for 35+ years what he believes is the most life-saving therapy ever developed for people with diabetes (other than insulin), and he said, "ace inhibitors" which, when diagnosed early enough, can extend your kidneys, and thus your life, for a very long time. So, I say, take it! It's well worth it.
