Time weeks symptoms and conditions

I've been taking Ace inhibitors for several years. Started with captopril, another whose name I don't remember caused marked depression (the others did not), and finally lisinopril. All caused the cough, which went away after taking it for a few months, and starts up again if I stop taking for a while and then resume. Other symptoms I attribute to ace inhibitors in general are a lack of libido, headaches, dizziness, and dramatic, but gradual, hair loss. (I am female.) At one point either the ordering dr or the pharmacy inadvertently doubled my dose from 10 to 20 mg(and I didn't catch the error for quite some time - weeks or months.) When I finally did catch the error, it explained my increased cough, headaches and dizziness, and severe postural hypotension. (I'm up and down a lot at work, and I felt I would almost black out when changing position.) I'm diabetic, and take it to prevent kidney damage. My blood pressure is borderline, and sometimes higher. Unfortunately, the ace inhibitor at 10 mg doesn't seem to lower my blood pressure enough.
