I think that losing weight may have contributed to drop in BP but I don't think it is the whole reason. I know my BP is raised just before going to work, so mental state has obviously got some influence. But one of the reasons may have been a dietary element. I had some raw beet with the intention of reducing BP but forgot to record results. I will now experiment and for the meantime will stay on Amlodopine until I am happy I have got BP under control.
