In this study, investigators will compare chronotherapy to ABPM. Data collected will include hypertension drug therapy regimen prior to and during the study, timing of medication administration, and dose, along with the patient's office blood pressure values prior to study and one month after modification in therapy. This will enable us to explore whether it is a practical endeavor to implement ABPM as a routine process for all uncontrolled hypertension patients or whether ABPM does not seem to provide considerable value over shifting the timing of drug administration.
