There is a way to lower it very quick.
Nitro pills under the tounge, can buy them in Madrid and most middle eastern countries.
But you are only cheating yourself, pass your medical, but the problem will kill you if not treated.
Lifestyle changes are the only way, reduce the alcohol intake, garlic pills even work.
Exercise more, don't have to go to the gym, just take a long walk everyday.
Giving up or reducing smoking is not a immediate fix, but long term it can help.
If the B/P is that high and not reduced you will have a greater chance of stroking out during any high periods of stress or work related tasks.
This from my AME and personal experience, reduce alcohol, exercise and drop some weight, it works.
