Is the Acai Berry good for Liver / Gall Bladder?

Hi Charlie. I recently developed Gallstones from 2 high risk pregnancies. I was Pre-Eclamptic. I was thinking of doing a Liver and Gallbladder detox flush and read about the Acai Berry Superfood on Oprah.com. I was wondering would this berry do all the cleansing I need or would I still need to do the flush. Also, I work in a small office with about 6 other employees and I travel via public transportation. I was reading about the detox and it said it was a 5-7 day process. Would a detox be wise for me? Or is there a flush I can do over the weekend lol? I was thinking of doing the following cleanse is this good or what? Thanx.
