Thank you, Anita and Dianetics for your replies. I have only been working on Level 1 up to now, and appreciate the extra advice from level 2, Anita.
I agree with Dianetics that exercise and diet are also important and feel that I am working pretty well on those already. One thing that I cannot do anything about it seems is the inherited nature of high blood pressure that I have. However, I will keep up with my SFQ and meditation and have faith that it will work. Thanks again for your kind thoughts and input.
