(Concern) Should I continue taking blood pressure medication?

It has been 5 years since I started taking blood pressure medication.

When I went for a health checkup five years ago, my cholesterol level was 146, so I couldn't undergo endoscopy.

I barely managed to perform the endoscopy by scheduling it three times in 15-minute intervals.

I started taking blood pressure medication from the next day.

I retired from my company and am taking a break while consistently exercising.

It's been over a month since I stopped taking the medication.

Every morning on an empty stomach, I check my blood pressure; if it exceeds 135, I take medication, and if it is below, I do not take it.

I'm wondering if it's okay to do it this way.

People around me are telling me not to do it...
