First, congratulations for choosing a natural path to heal your health conditions, especially Liver Flush.
No stones in your first flush does not mean much. It definitely cleaned your liver and gall bladder. As both posters said above, sometimes it takes a few flushes to get good results. I was very lucky that in first Liver-Flush I had hundreds of stones and my Depression went away in one flush. So please flush away, every two to three weeks you should flush. I suggest you follow Dr. Clark's protocol to the T.
I am also glad to hear that you are eating veggies and fruits. It has the power to heal even cancers if we do not deviate from that path. So continue eating raw foods as much as possible. It will take a long time to cure everything that you suffer from now. It takes a long time to get into a diseased state.
Also do not drink cold stuff from the refrigerator. Your liver does not like cold things. Try and drink freshly squeezed juices everyday.
Hot and warm foods and drinks will help your lungs and breathing this also include spicy foods. Eat cayenne pepper everyday.
Other few things you can do is to have apples, take Colloidal Silver , turmeric and gold coin grass, beets and everyday. Avoid all milk products, cheese etc.
You need to do all these things persistently to have your health back.
