Liver Flush during whole body cleanse?

Hi,
I started a 2 week boxed cleanse called "Ultimate Cleanse and Detox" by Michael's Naturopathic Program one week ago. It was the one the guy at the health food store had suggested, so I bought it, and haven't felt too bad however my eyes are very jaundiced, and I feel more tired than I did before the cleanse(My 2 symptoms before I started, which have only worsened.) I'm wondering if I could do a Liver Flush during the cleanse, or possibly right after? I really want to get feeling better sooner than later, and want to know what is safe and effective for aleviating my symptoms.??

Thanks.
MJ
