Wow, you're way ahead of me! I just use the 2 quart bag. I usually add about 4 tablespoons of the organic apple cider vinegar to the water and make sure that it's warm. I've also done a wheatgrass (my personal favorite for its effectiveness), a garlic, and a coffee one.
Oh, and I use the organic apple cider vinegar. Bragg's is a good brand that they sell and hey - I bet you have it since you're only a hop skip and a jump away from me!
