They say you can get other worms from dirt, but I've never heard of getting pinworms from dirt.
I don't know anything about DS but thats great that you've had good results with it. Seems like you've got it all under control.
I am taking BF's DeWormer now, on my 2nd week. Before that, I was on EXHumaworm. I didn't notice much difference on that though. I just thought a colonic would really help to clean me out. I never had bowl or constapation problems, in fact I eat a good high fiber diet. Thanks for your suggestions.
