Good sources for liquid Bentonite and psyllium include Yerba Prima and Sonne's. Since everyone's tolerance and progress on the cleanse varies it's hard to say how much you will need for a month's supply...perhaps others can provide input.
You can purchase psyllium as whole husk (my personal fav) or as powder. Mix 1 teaspoon of psyllium powder (or 1 Tablespoon of whole husk) + 1 Tablespoon of liquid Bentonite with 8-10oz water or diluted juice, shake and drink immediately. Follow this with another 8-10oz of water. I don't advise mixing the shake with 16oz of water....it's a lot to get down before the mixture starts to gel up.
You may want to focus more on vegetables than fruits in your diet. Fruits are definitely a problem if candida is present and...even if it's not...you want to watch your Sugar intake. There's lots of good things in fruit, but the Sugar is there, too.
