And I change my dosages and combination quite often.
I thought about not taking my verapamil for 2 days and check my bp twice a day to see what it is.
That's not a good idea becasue it takes FAR longer than 2 days for the body to settle back to normal. IF you are going to ascertain the effect of going without a drug, do it for at least 30 days and monitor your BP often. Keep good records so that you can then see an average BP over time...then adjust your dosage.
MOST people take at least 2 drugs for hypertension.
