Roundworms. I had them years ago. I think I may have had them for more years recently. When you are quiet at night you can feel them moving around in there. I have been on the program and think I have most of them. Didn't see them come out. They must have gotten ground up. I take bromelain at nite when I get up around 2-3 or whenever. This stuff is good to digest any kind of protein anywhere in the body. Good for bruises and blood clots. If you have vericose veins it would be good to take. Anyhow things are much quieter in there now, but still feel some movement. Probably the big ones escaped the poisoning. I may try that Paragone, as I'm not sure that the stuff I bought, like the Black-Walnut , is any good. It is not light green.
