There is a need to do a BP charting before starting any anti-hypertensive medication. I would recommend you to measure your BP twice a day for a week and make a chart for the same.
Till then stay calm, meditate, maintain your sleep wake cycle and take 2.5-3 L of fluid a day to curb any dehydration.
Thank you for asking.
Stay healthy. :)
