Advice on liver flushing plan

I am starting my Liver Flush today and am wondering how I should go about it. I'm going to do the Hulda Clark one this evening. My main symptom is lack of good sleep which I am attributing to my liver being over toxic. I didn't have problems sleeping until I starting cleansing. I have just finished a parasite and bowel cleanse.
I want to do 6 I am guessing and wondering how I should I space them out? Should I do them every weekend for 6 weeks or maybe wait until I can tell I need another one? Also I could not find HCL on it's own unless you can think of a store I can go to look. I realize I can buy online but I was wanting to start today. I ended up buying betaine HCL at wholefoods. Any additional advice from your own experiences?
