I have tried to use the A, and didn't make it, check out the health food stores. I can get the "NOW" brand for $25 a gallon, which is a great price, and it makes a huge difference. I would even mail order it if I can't get it. Buy a little electric citrus juicer- it makes it alot easier. Not sure how much weight you will lose, I don't have a scale, since they tend to talk to me and ruin my day. I usually lose 3 sizes or so, if that helps.
