Yes, these are liver-related symptoms. Make sure to prepare yourself poperly for the cleanse (including the stone-softening prep, colon cleanses before and after the flush). See directions in The Amazing Liver Cleanse.
Without cleansing the liver bile ducts others detox methods can backfire, since toxins try to leave the body via the bile ducts and GI tract. If there is only little bile flow, the toxins remain in the blood and lymph making your body and eyes tired and congested. To help with the healing make sure to sleep before 10 pm and eat your main meal at midday (more details in The Key to Health and Rejuvenation).
