It's never too late to start the shakes. You can get both b and p at any health food store, or you can use several premade products. B is also sold as Sonne's #7, and the P is usually right next to it - both are in the cleansing section. You'll pay under 30 for both. Not very gross - thick and sludgy, but not much of a taste. You must start off with one a day and drink drink drink lots of water - if you have regular bms then you increase to two, lots of water again. If you have reg bms on two you increase to 3, etc etc etc - the most you should do is 5 or 6 a day, most people stop at 3. Hydrate, hydrate, hydrate! You can do them with a mc, or you can wait until you're done and take them when back on food.
