Steely - you will be surprised how much can happen if you just dedicate the time and faithfulness to using SFQ. I have been using the home course study for a couple of months and have noticed some general improvements in my overall health. I had no complaints to speak of when I started the course, just wanted to increase my stamina and general well-being. I'm sleeping better, by digestion seems better, I have more energy throughout the day. I have been able to use the exercises to alleviate muscle tension and pain in my body, too.
I can tell you that by just doing the exercises and the meditations that whatever your body needs, you will notice improvements in that area. I would suggest that when you do the exercise of inhaling universal energy and exhaling any illness, pain, etc. from your body that you imagine your blood pressure coming down to normal.
I have not taken any of the courses with Chunyi Lin, only the home study course for level 1 & 2. I am using the level 2 work on others very successfully. It is wonderful. Good luck and keep up your regular practice!
