Hi Sunshine,
that's a very good and a very effective combination of meds. You should be just fine. Sounds like you experienced a bit of a white coat hypertension at the doctor's office! What were your average readings at home?
Good luck with your drug combo! You will not have to pee every 5 minutes though you might have to get up & go a couple of times every night (unless you do that already, anyway, without the diuretic).

You'll hardly notice a difference in the frequency of trips to the bathroom during the day.
