A quite wonderful post on the management of HTN. Well written and just the points we need to know.

You have pointed out the non drug management of hypertension. These are really important. Reducing salt intake, giving up alcohol, changing diet menu, doing regular exercise all are necessary to keep pressure under control. If with these measures the BP comes down, that's the best thing. But we should keep in mind that despite all of these measures, if BP still remains high, we have to go for medicines.
Note: I think you can add give up of smoking as a measure too
