I am not qualified to advise you, but I'm happy to share my experience.
In 2007 (age 52) I was overweight and in a job I found very stressful; a routine healthcheck at work picked up that I had high BP and frequent tachycardia.
I elected to make lifestyle changes before medicating. Changing job very quickly got me back into the borderline high BP region. Years later I decided to gradually make more changes, mainly to improve my quality of life; giving up alcohol, coffee helped as did reducing my weight (10kg lost). Reducing my salt intake made a big difference.
If I eat a takeaway meal now, or drink one coffee I experience the old familiar symptoms of high BP.
For me this works, and is easy, but I'm aware that giving stuff up can be difficult for many people.
I'm now 67 and use no medicines.
