No salt, exercise of course, I would not say cut out drinking unless you cannot go down to a moderate level which (can) be beneficial.
And if, despite everything you cannot get it down, do NOT procastinate, get on medication, it's not that big a deal.You can fly with it.
Or you can do what I did and delay too long (because I was afraid someone would find out) causing myself a permanent though minor cardiovascular problem.
All sorted now, and taking daily medication ( there is no shame) Take care of yourself.
