Funny you mention getting off of bp meds. I'm on 2 types (Lisinopril & amlodipine, small doses, once daily) though I have noticed my blood pressure has been lower lately.

I know I've changed my diet the last year due to finding out I have Meniere's Disease (less bread, diary, sodium, pastas and eating more oatmeal with different fruits), and I'm on a diuretics for MD (Hydrochlorothiazide) since last year, and I also started taking Quercetin (with zinc, c & d3) months ago. So I looked up Quercetin and it does help lower bp according to Healthline (link below). When I looked up diuretics, I learned another thing, they can help lower bp also. One of those "slaps forehead" moments, lol. I keep checking my bp a few times a day and if I notice it is edging up I will take one (Lisinopril) bp meds. But I've been going days without needing to take one. Not sure if not taking my bp meds everyday is good practice or not, but I thought I'd see how it went.
