I read a post a while back by a guy who claimed to be managing a long term condition he had via homemade blood monitoring and pills containing something that earlier trials had shown were effective at managing the condition (I don't think it was diabetes, but it had a similar flavor to treating diabetes with something other than insulin.)

He explained that he eventually went blind in one eye because he had miscalculated the dose of something in his pill and eventually OD'd on it.

My reaction to the story was: "This is fantastic. More people should be doing this." (Obviously not the going blind part.)

What I do want is for it to be more widely recognized that we have in fact reached a point where it is possible for people to make their own blood tests, identify promising treatments in the scientific literature, and make their own medicine. I can't help but think that if that guy had been sharing his treatment with a like-minded community, someone else may have caught his dosing error.
