147/84 is this high blood pressure that needs meds?

Re-check: 147 is high systolic BP and 84 is pre-high diastolic BP. I therefore suggest a visit to a medical clinic as soon as possible to re-check your blood pressure professionally & for consideration of treatment with meds. In the meantime avoid caffeine, alcohol & partially hydrogenated vegetable oils, get adequate rest & exercise, eat a low fat diet rich in veggies, fruit & poultry & fish without skin.
