If it's been two months since you've done your last cleanse, I'm sure it would be Ok to go ahead and do another one. Humaworm is the only one I've seen who says you should wait that long. Every other cleanse I've seen, it says to wait 5 days in between cleanses. That makes more sense to me, because I've built up a tolerance to different herbs I've taken in the past, and it usually takes only a couple of weeks for me to be able to effectively take them again, and have them work. I could see a month maybe, of waiting, but I cannot understand waiting 3 months-nothing stays in your system that long! But Humaworm may somehow be different, I don't know-haven't used it yet.
