I did not do the laxative tea every night, so I can give you my first hand experience. :)
I found that the SWF (Salt-Water-Flush) was okay alone - it did the job. But the few nights I did do the tea, and then the SWF (Salt-Water-Flush) the next morning, seemed to be the most clearing of all. So I think you would be okay with the SWF (Salt-Water-Flush) alone, but for optimal benefit, you should do both.
