I would try the laxative at night and SWF (Salt-Water-Flush) in the morning. The first time you do it, you may need to give yourself enough time in the morning to feel like you can go to work without having to hit the toilet, this takes some timing and knowing how your body works with the cleanse.
The purpose of the laxative and SWF (Salt-Water-Flush) is to get the toxins out. If you do not do them, you will feel pretty bad, as the toxins stay in.
I had a lot of resistance and fear at first also, but it turned out my fears were worse than the actual experience.
