I believe the book does mention doing the lax tea morning and night and also many folks on the forum do that as their regular Master-Cleanse protocol.
If you're asking if it will hurt or harm you I doubt it. All I can go by is my personal experience of getting nauseaus and feeling crampy all the when I had to do it cause the SWF (Salt-Water-Flush) was not working on my most recent 21 dayer. If you absutly can not do the SWF (Salt-Water-Flush) then doing lax tea morning and night is prolly your best course of action >buuuuuuut< If you can use some of that good attitude and positive energy you've been diseminating on this forum to make yourself do the SWF
at least 2 or 3 times a week I believe you'll do yourself some good by "efficiently" expelling the accumulated toxins from your system using the SWF.
