I am controlling my blood pressure well most of the time(under 130/80) by using 1 tablet of lodoz (6.5 mg of hydrochloridediazide and 5 mg of bisoprolol) and 2 tablets of nifefipine(10 mg each sustained release). It is a bit inconvenient as i have to take the nifedipine tablet once in the morning and once in the afternoon. My doctor gave me a choice between the current approach and taking a tablet of 30 mg nifedipine gits for 24 hours' control. I kind of hesitate to go into the new approach for fear that if it does not work i will not be able to come back to the old approach.
