I am doing this without the swf this time around. Just being sure to drink plenty of water, and take the senna tea. I think, as long as you are having bms it is ok. I had a lot of trouble with the swf last time, because I would just keep absorbing the salt. I think it is worse to take the swf and not pass it than to skip the process. Others may differ- I know the swf is highly valued here, and seems nifty, but I have only ever managed to pass the stuff once. Most times I just bloat and feel sick. That can't be good.
