The main difference between 1000 and 3000 is the addition of DMSO on the skin -
To the best of my knowledge there is no interaction with MMS1 and psychotropic meds - which leads me to believe that if 3000 is contraindicated with those meds, it might be because of some issue with DMSO - Such as, maybe the psyc meds put a very heavy load on the liver, weakening it, and DMSO might make it more difficult - or maybe there's something in the DMSO that interferes with the way the psyc meds work. I just don't know. I've never heard Jim Humble state that you shouldn't do DMSO and psychotropic drugs - he's only said that when you start on DMSO, to go very slow and be sure there's no discomfort in the liver area - that some people may be allergic to it and not know it. I might go back to the blog source and see if they can tell you where they got their information -
It's obvious why DMSO would be good for fibromyalgia, because it relieves soft tissue discomfort -
