My friend 30yrs claims that he had high blood pressure. Diagnosed by a doctor who after checking him found he was 170 /90 -. She prescribed welbutrin and said there is no way this can go down anytime soon without drugs.

Now he claims that after a healthier diet change and regular "hardcore" working out that a week or so later, he has had regular readings since.

Is it even possible to average in the 170/90 - and 10 days later to be averaging in the norm.
