I use 'bija gentle senna' tea at night because it doesn't cause the discomfort that I felt when using 'smooth move' tea which is a much stronger tea. I also found that the SWF (Salt-Water-Flush) was quite unpleasant the first two days but has become much more pleasant to the point that I don't mind it at all now at day six. I'm also considering doing the lax tea every other night because things are moving well enough that I don't feel that it is necessary everyday.
