Hi Road! Did you check out FF's posts on probiotics & also chack out various cleanses & stuff? I agree, it IS confusing, there's so much conflicting info.
The first thing to do, though is dietary clean-up. That's my opinion, anyway.
Now, what you really need to do is post a new question on "Ask Curezone"...or "Ask Dennis Hardy", he's a naturopath, he's quite curt, but he does know his stuff. He also hangs out in the chatroom in the evening...
I am not an expert in any of this, but I can point you to people that I believe are quite knowlegable> And the best way to get your questions answered is to post a new question....threads get forgotten when they are a few pages back... :)
