I am having good results with reishi. I added in cordyceps about 5 days ago. I have been able to eat a greater variety of food and then because of that I was able to cut out gluten and dairy. I have less fatigue and aches and pains, and don't have to urinate and drink water so often. The most amazing thing that has happened is that I've been whistling for about 3 days now, which I only have done when I feel okay. I hadn't found myself whistling for several years now. It didn't hit me until about an hour ago what that meant. I am getting better! I even went off my gluten/casein free diet on Friday night, but still am improving.
I saw a friend with similar issues on Friday night, and she said, quite coincidentally, that the only thing that has given her relief is the coffee mixed with reishi and cordyceps that you may have seen at iherb or on the net. She had tried reishi tincture and capsules but the stuff mixed with coffee is what helps her, not only with energy, but also with pain. That made me think that reishi works better alongside a particular medium, and I had found that a dropperfull of it in decaf coffee works really well, but in oolong tea or dandyblend coffee substitute, it just bothers me. I've been taking aspirin with mexican coke since last spring when I found information that aspirin gets uric acid out of the body, and remembered that coke potentiates aspirin. Aspirin and coke almost always makes me feel better, but when it doesn't I take some activated charcoal. I tried reishi with coke yesterday, and they do work well together. I would rather take reishi than aspirin, as it's benefits far outweigh aspirin.
I also ordered some chaga, can't wait to try that.
