That was an unexpected turn. Technically yes, any surgery requires a stable blood pressure. I wouldn't want you to go with the medication, it can cause you other problem later. Drink lots of water(off the beer and caffeine) and give it a flush, your blood pressure can reduce back to normal in probably less than a week.
Hmmm... That arm rest did reminded me the barber shops back in the 90s 🤪 yes, those were the days the barber is smoking and I can smoke and enjoy a haircut as well 🤣
