Another remedy I have been told works quite well is acupuncture. You might want to try it. Apparently, they can tell if it will work right away, so you don't have to invest a lot of time in it if it doesn't.

You are so close to goal, I would think losing weight might not have a huge effect. In me, my blood pressure went up at my lowest adult weight and stuck there, It came down when I was much heavier, so it's not always tied to weight.
