All bp meds have side effects, some really bad. That Tekturna sounds really bad. I quit taking all bp meds a few months ago.
I had been taking Metoprolol for a year or so and I developed diabetes like symptoms from it, plus had really ugly red leg rashes on both legs, and they didn't go away until i quit taking the meds!
I don't care what doctors say that we all have to take meds, no we don't.
I started taking Raw organic Apple cider vinegar (ACV) around April of this year. I take it 2-3 times a day, with stevia and water, and it helps lower bp naturally. It helps thin the blood according to a doctor, it's similar to what an aspirin a day will do. Although ACV is better. No stomach bleeding like with the aspirin.
I saw a book on Amazon recently that is called "Prescription Alternatives. Hundreds of Safe, Natural, Prescription-Free Remedies to Restore and Maintain your health." by Earl Mindell. For every ailment someone has, it has a list of what to do, and the alternatives to all the pills, plus certain vitamins to take,etc. You can read excerpts at the site.
I went and bought it and am now implementing many of the things in it. I have a long way to go, after having been on bp meds for the last 7 years.
As far as believing the medical establishment, a better bet would be to do alot of research like i did relating to bp and general health. Putting all your faith in a doctor will only result in you taking endless amounts of precriptions and never really getting well. Because all pills do is mask the symptoms and they never cure you. Once you quit taking them, you still have the problem. So that's not good. Plus you end up having lots of side effects, which makes you feel worse.
