One thing that came to mind as I was reading your post is that if you have only been concentrating on liver cleanses, you probably need to clean out your colon, too. A kidney cleanse, parasite cleanse and Colon Cleanse are recommended to really get things clean and working efficiently.
It seems a little scary to me to think of you doing them nightly. Liver Cleansing is a very powerful cleanse. I think the advice to do them at least two weeks apart should be heeded unless maybe you do one or two back to back in the case of a stone being stuck. You may be doing more harm than good to your body, by putting it through that so many times. Not to sound patronizing, but please be careful.
