Delighted to hear of your appointment for the stents! Patent jugular veins are a sine-qua-non for the healing process to kick in.
I had the liberation procedure twice in the last three years (balloon dilatation, no stents) with remarkable improvements.
I cannot give medical advice because it would not be ethical. What I can do is to tell you what I have being doing: daily assumption of anti-radical natural substances (essential oils, vit B complex, vit C) and moderate exercise (maily walking and cycling).
I was diagnosed in 1986 and have being working full time since as cardiac surgeon.
