HI there, I would not worry too much. Andy Cutler says that people can chelate for 3 days up to a week if they wish and take the same amount of time off for a break (or longer if they want). E.g. 3 days on, 3 days off. 3 days on 7 days off, or one week on, one week off. 4 days on, 10 days off. There is no real hard and fast rule to that as such, so long as the person is chelating for longer than a day or so and has the same amount of time or more off.

The frequent/continual dosing is the most important part of his protocol. Though his book says one week on, one week off, Andy does not strictly stand by that, people can adjust it as suits.

Some people may chelate on the weekends and then have the week off if they get too many side effects during chelation. Some people who actually feel better during chelation, may actually want to stay on it as long as they can. Though unfortunately lack of sleep is not the best to go on too long with, plus chelation can be stressful, so it's not wise to go too far over a week.

I hope that helps.
