@Magisham , I'm really pleased your husband's BP seems to have moderated a bit. You seem to work so hard for him.
If he is a stressy person, it could be worth his trying some of the reraxation things others have suggested, or a bit of hypnotherapy. I found hypntherapy really excellent, when going through a very stressful time. I
The lady I went to was very good, and listened to what was stressing me, then did a little bit of hypnosis on me. I immediately felt different. It was a bit like someone had lifted me by my head and given me a good shake to get rid of all the knots in my muscles and loosened my chest.
The first session was all about learning if hypnosis suited me. After a few days I had a telephone session to feed back too her how I had felt in the couple of days that had passed. I felt great!
I had one more session where she tweaked some of the messaging she was giving me, and recorded the session. I left with the CD she had recorded to use at my will. I still have it now, and I have converted it to MP3 format, so that I can still listen to it when I want to. I very rarely feel the need to listen t the session, as I can deploy the techniques in the messages without it.
I know your issues were really about his BP, but I know I certainly feel much better when I'm not stressed.
