"Unidentifiable objects"...hmmm...could it be that you are passing parasites? As parasites are killed off they can release their own toxins into your system. It's possible that your icky feeling is a result of getting rid of the critters. Not to worry...you will feel better! Drink lots of water to keep flushing toxins out, and - if you haven't already - definitely do a good colon cleansing.
Actually, the Colon Cleanse and parasite program should be done prior to liver cleanses/flushes for precisely this reason. That way the channels of elimination are wide open so that toxins can be expelled more rapidly and not reabsorbed. Some of the more uncomfortable cleansing reactions can be avoided or minimized by following this order.
