Anyone (else) run into the problem of sleepiness when adding lisinopril
(10 mg) to HCTZ (25 mg, for one month)?  I took the first pill in mid
afternoon and when I got sleepy, decided to "take a nap".  I did wake up
twice, but by the next morning had slept 11+ hours (6+ is normal).  Other
differences I noticed were clumsiness, plugged ears and a runny nose.  (I
do have an Onrom 711 and while my sbp had dropped about 15 points, it was
in normal range.)

Called the MD's office and he was sceptical that lisinoprol could cause
those symptoms.  He offered the options of continuing for a week or being
switched to Diovan.  (My next scheduled appointment is in 4 weeks.)  Since
the main reason I find to take Diovan is that it is less likely to produce
the cough side effect, I opted to continue, but I've reduced the dosage to
approx. 2/3 pill and the HCTZ to 1/2. After two more days, still have the
side-effects and the sbp is back up in 140-155 range.

I'm now understanding why people drop bp treatment.  I'm female, 70,
otherwise in good health and ISH seems to be par for the course.  I'm
physically active (ok, not as active in the winter) and with the HCTZ
alone, I was not pleased with my reduced exercise tolerance.  Imo, there
must be a point of diminishing returns in reducing bp to the ideal range
in some patients.  Otoh, I do appreciate that treating high bp must be a
frustrating experince for MDs; similar to treating excess weight.
