I have similiar uncontrolled blood pressure. I've spent time with pcp's, cardiologists, and nephrologist. I also find that blood pressure meds will work for a time then fail to work while my blood pressure rises. In the 90's I was running 160's/99 with about five meds maxed out. My pressure would increase to 180's at times. I also notice if I quit taking the med's my pressure would decrease. I wouldn't suggest doing this without monitoring it closely.
I did find one thing that would reduce my blood pressure....and only one thing. Oh, by the way, I also tried all sorts of eastern style medicine without success but with enlightenment. This included acupuncture, acupressure, chiropractics, diets, reiki, massage, cranial sacro, chinese energetics, prayer.
The only thing that actually worked for me was doing the "Master Cleanse" diet. Look it up on the internet. I did this diet for 5 days and it would drop my BP to 120/80 without meds. That was in the nineties.
I had my bp down for a while without meds(140/80's), but then it started creeping up and I wasn't watching it(now in the 2000's).
It got high again and I went to the doctor and of course they put me back on meds and everytime I see the doc I get new meds and increased doses of my old stuff. I thought I'd let this doc give it a try since I also damaged my kidneys some since my bp was so high.
I'm current talking the following meds and my bp is anywhere from 180/99 to 240/120. Not good....
4mg Doxazosin, 200mg Metoprolol, 60mg Furosemide, 50mg Hydralazine, 10mg Enalapril, .3mg clonidine
Since the increase of meds hasn't seemed to help I started the "Master Cleanse" again. I'm on my 3rd day and I hope I will see my bp drop soon.
The biggest problem with the Master Cleanse is that I can't live on this. As soon as I start eating regular food my bp goes up. This time I'm going to start with just raw vegetables and fruit when by bp is back to 120/80 and I'm going to keep a good journal of what I can and can't eat.
Also, I'm 48 and look like I'm 30. I'm in good shape but I haven't been good about keeping my cardio up thought I work and physical job every day. I'm not overweight and people would never guess I have high bp.
Hope this helps someone and maybe give data back if you find something other than the Master cleanse.
