high blood pressure
"On 10mg/day for a week and favorably impressed.  Has BP between 115/72 and 135/85 for most of the time.  A bit lightheaded - more so for an hour or two after taking it.  No other side effects.  Feel good and thankful BP is down.  Would like to try 5mg at 8am and 5mg at 8pm.  Will discuss this with my doctor. But so far, absolutely no complaints - just a positive experience."
