I'm kind of a newbie so please bear with me here. First some facts: -- I haven't had a cold or any infection at all since I got ME/CFS in 2004. Doesn't matter how much people cough at me. -- When I become allergic to our cat I get a great energy boost. -- Got lots of autoimmunity (RA; MS, psoriasis etc) in my family. -- Swine flu vaccine left me feeling much better for a month. -- Goji berries, that are supposed to stimulate the immune system, makes me feel like shit for four hours, with aching lymph nodes, heavy feeling over my chest and achy throat. I draw the conclution that what I need is an immunosuppressant, not a stimulant. Still, the stuff mostly mentioned here, like iisoprisine, are supposed to be stimulants. Anyone able to sort this out for me?
