high blood pressure
"I was very happy to find this medicine.  It is inexpensive, works well, has been well researched, and has a noted negative correlation with senile memory loss.  My impression is that I have good mental sharpness, and I have come to trust it after using it for well over 2 years.  (My mother experienced profound memory loss, which she attributed to her blood pressure medicines, so this research was of interest to me).  The downside of this medicine is that it must be taken every 8 hours, so it requires better attention, but it works well, so I am fine with that.  I did experience the dry cough that many new users are said to experience, and this was a minor annoyance for perhaps the first 5 - 6 months, but it was like a tiny tickle in the throat, very minor."
