Starting my first ever flush today after 10day MC.

I have done The Master Cleanse for 10 days, today would have been day 11 but I'm starting Hulda Clark 's Liver Flush today. Does anyone have any experience with doing the Master-Cleanse before this flush? I did a salt water flush this morning and I've drank water and had a little OJ - 1 orange fresh squeezed but am now fasting. I am nervous about this but also excited. I found Black-Walnut tincture but wasn't able to find ornithine. Is it really that hard to sleep? I hope not. Also, an unexpected meeting came up for 11:15am tomorrow. Am I going to have to reschedule it or do you think that I will be able to leave the house okay?
