Agreed with Archus. I'd add that you need not to be afraid of vomiting when it comes to it, since you will feel better afterwards. Suppressing vomiting is suppressing a good way of elimination, which your body obviously wants to utilize.
If your breath isn't sweet, etc, means you have more to detox than the average case, which was given just as an example. Besides in the days of founding the Natural hygiene ppl were far less toxic, than the average person today.
