@jenatsky Thanks, but not talking daily differences -- just morning, afternoon or evening high or normal BP reading differences, and making only slight med adjustments. On 3 different meds -- 2 prescribed for twice a day I take morning and afternoon or evening, and the other in the morning *if* BP is over 111. So I have the opportunity to skip an occasional dose at my discretion. And my levels have decreased overall since these were first prescribed following stroke 10 months ago. Will consult my doctor.
