I hear a lot of talk about this full moon business. I take the MH Dewormer and MH responds that any time is a good time to do the cleanse. I get the feeling that people are so out of touch with nature anyway, that the full moon means practically nothing. But if you are on the 30 day dewormer you would hit a full moon anyway at some point during the cleanse. It sounds nice and everything, but I think it's more important to just do the cleanse.
