Thanks for responding. Actually, I was wondering both. How you could tell things were working by either the addition of herbel supplements or by doing a liver cleanse? I'm going to try the Liver Cleanse Salad for 7 days that I read about and I was wondering what to expect with that. I think the herbal supplemnts are working because my tongue is not as yellow...and actually I do sleep better too :) How long are you supposed to take supplements for and which ones are you taking?
