Nanamac I've been in a similar predicament to yours. On BP tablets for 20 years, last year it suddenly went up. It took a visit to a specialist plus 3 different tablets to bring it down and this took quite a few months. I too bought a monitor, at first I kept checking it, eventually relaxed about it and I now just check it twice a week, once on Monday morning and the other on Friday evening. Like other posters I had to take a cocktail of lisinopril, amlodipine and a diuretic. If you are overweight, losing some weight can only help.
