2. Senna is fine short term. It can be addictive (that is, your bowels won't function without it) if you use it for weeks and weeks. Most of our laxative teas use Senna.
3. You should stop the SWFand the teas after you start drinking the OJ (you can do it on day 11, or the day you start drinking OJ, but you should stop after that) because you need to get your bowels working on their own again. It may take a few days to get a bowel movement, or you may get one right away when you start eating. You can drink the lemonade once you start drinking OJ to supplement.
