I personally had a lot of success using cleansing products by renewlife
You can check out their products at http://www.renewlife.com
I would start with the "cleanse smart", it's the colon cleanser product that REALLY worked for me, but I can't really give you advice on the others because I haven't done them, except for candigone, which I'm using now and I do seem to be getting better, but I'm nervous about it's effectiveness since I have a relatively severe case (in my opinion) so that's why I just ordered "candidate" by nativeremedies.com Also I don't know how they might affect you because of having your gallbladder removed. I also want to do some heavy cleansing of my own but have put it on hold until I get Candida under control because I'm a raw vegan, or used to be and had to stop because over 60% of my diet was natural Sugar from fruit which made my candida problem worse. So hope that helps and good luck with your cleansing!
