They are dreadful, I am sure they do more harm than good. My OH was also advised to go onto them, he made lifestyle changes by cutting out carbs, sugar and eating more healthy fats, full cream milk, butter, nuts, veggies etc and of course started walking a lot, his last blood test showed hugely decreased levels and no need for medication, the Dr did not quite know what to say so merely advised for him to keep doing what he has been. And as an aside, he could ditch his BP tablets that he had been on as his levels normalised.
