If you go to the link posted at the end of the first post you will find the FULL article that is focused on HIV/AIDS treatment options. It is one of the best articles/treatment options I have come across, not just for HIV but all kinds of health issues.
As for the stool floating as noted in the article, when there is a good supply of benificial flora in the digestive tract then the stool will float, see the article for more on that. However, upon further research stool should float and gently fall...if the stool kurplunks and sinks like a weight then there is not enough benificial flora.
Do read the article there are really great common sense approaches that are vital to improving health, not just for the immune compromised but for anyone who wants to improve their health.
