Hi everybody. I'm a few days from reaching 20 days, and I want to go longer than that. I've read other posts and it seems that optimal cleaning occurs between 20-30 days. (This makes sense to me, because I feel I have a ways more to go). But, is this correct? Is there any chance that going longer than 20 days is harmful? Has anyone out there gone over 20 days? Anyone gone 30 days? I would love to hear about different experiences of continuing a cleanse of maybe 30. Many thanks!!
