Cleansing while employed

I am unable to take time off work for an extended cleanse, so I would like any advice that anyone has for cleansing while employed. I do tend to have strong herx reactions. I started on Colloidal Silver two weeks ago 4T a day, and I got so sick I thought I had stomach flu until no-one else in my family got sick. I cannot afford to miss work. I am interested in master cleansing, liver flushing, Bob Beck protocol. Any advice at all much appreciated. I work 4-5 days a week, early morning shift as an RN at a jail (5:30-11:30). Bathrooms are few and far between.
