high blood pressure
"I have "auditioned" eleven blood pressure medicines.  So far, lisinopril is the least objectionable.  For one thing, it really works.  My blood pressure is down to 117/78 at 10 a.m. This is on only 2.5 mg, which is 1/2 of the smallest tablet they make. Two months ago, before lisinopril, I went to the ER because I was at 170/104.  I do have a slight increase in head pain where I have had repeated craniotomies, but it is definitely less than any of the other medicines I've tried.  I also retain water, have some hair loss, have lower blood sugar (not good for me because I am hypoglycemic), and somewhat wakeful sleep.  But the worst symptom is that it makes me impotent to the point of penile atrophy.  A good medicine for women."
